Hey, just FYI I have discovered that the secret to better SDs in 300 blackout subsonic is to seat the bullets as deep in the case as you can rather than to mag length. For example I run 208elds at 2.15 oal and 242gr Noe cast at 2.05oal. Seating the 208elds at 2.26 gives 100fps swings, seating at 2.15 gives single digit SDs. Give it a try if you ever load subs again.
That makes me think back to the issues I had with powder position. If I held muzzle down before shooting, I got one velocity. If I held it up, I got something completely different. Really weird inconsistent ignition with certain powders. A nice full case of powder always seems to ignite better. I did some testing with case fillers to take up the excess space, but just seating things deeper accomplishes the same thing! That would be my best guess at a root cause of your success.
@@JohnnysReloadingBench I had the most success overall with h110 for my sub loads, cfeblk and lilgun have been respectable as well after I discovered the “shortest possible OAL” trick. Lilgun is a quirky powder but if you can find a load that works it definitely wins the least gas in the face award while shooting suppressed. at least in my gun.
I’m not a reloader unfortunately, yet…, but I remember back in the day when guys were running subsonic 300 Whisper they said that hey loaded a wad or case filler such as saw dust. I’m pretty sure they did this with bolt guns and single shots and that saw dust would clog up the gas port. Just a thought.
@@JohnnysReloadingBench you will not get reliable velocities when the gas block is not present. The gas excaping the gas port is uncontrolled. Im a little late to the party. Thanks for what you do. Been following you since you were at 12k sub. Great Info!
A great use for the 150g gold dot (blk version) is the 300 HAM'R. It can push the bullet between 2250-2300fps at the muzzle. Given the performance at low velocity, the increased velocity from the HAM'R puts the bullet in it's optimal performance velocity range. It makes a great deer cartridge inside of 200 yards. A modern 30-30 if you will.
First off, big fan of the vids. I learned how to form and reload 300 blackout watching your videos. I got mine up to 1800fps out of a 10.5" BA barrel using CFE BLK. It is a full case load, on the razors edge of compressed, at 2.204 oal with no pressure. Shooting .5 MOA and single digit SD. Several whitetail and hogs down. All hunting under or barely at 100yrds.
Cool video, your loading methodology and videography are impeccable. I bought a 300 blackout upper for deer hunting in thick hardwoods and love it. I only have time for shooting factory loads now but my brother has dies. With the constant barrage of new calibers I worry that the blackout may be harder to find in factory loads.
I’ve used the 150 blk variant in my 300 Hamr and it was excellent. I was never able to recover a bullet but a good amount of terminal damage. Best group is about 1 1/4 inch @ 100
I worked a load up for my son's 300 BLK last summer. 125 gr. Cavity Back MKZ with 18.0 grains of H110. Just under 1 MOA @ 2185 fps with a SD of 3.5 fps. He smoked an 8 pt. on Christmas Eve with this load. 65 yards and dropped him in his tracks with a pass through behind the shoulder shot. I'm thinking about trying these in 6.5 Grendel.
I have the Lee APP and I invested in the roller handle and what a world of difference it made when resizing brass. That knob handle can really beat your hands when doing a large batch.
If you have not seen it yet, the Sig Sierra 3 (and 6 if you have deeper pockets) riflescope is pretty amazing. You can save various loads in profiles for a quick switch between different loads. I have one on my .458 socom.
FYI there is an entire 38 page thread over on 300BlkTalk in the main discussion area started by user dellet with tons of good info on loading this bullet. I would link, but YT doesn't like links. My favorite load uses Shooter's World Blackout and CCI#41. That powder is roughly 100fps per grain and behaves really well when at or near compression. These are super accurate out of my 14.5 1:7 barrel consistently grouping under an inch when I do my part. I recommend somewhere between 19.00 and 19.50 as a starting charge with 2.200 OAL. You can safely push loads to about 2100fps (right around 21 grains) without much trouble, though it will start to compress after that. If you are really ambitious with a bolt/barrel you trust over 60kpsi, I've gotten 2200fps before I stopped, but I wouldn't recommend unless you are confident in your equipment.
Yep shooters world SBR Socom powder is it my go-to powder for 150 grain I'm also running a 14.5 barrel but with 1in8 I'm averaging 2105 with a Hornady FMJ
o yes thanks for doing this test. i bought a few boxes of each when they were on sale. had not loaded them yet. loading them with lil'gun powder i hoping get a nice load close to 2000 in a 16 in barrel. at lest that is is my goal. cheers.
Great video man. I put a300 blackout together because of this channel. It’s now my favorite thing to shoot since I got a can especially. Learned it all here. I would love to see the gel tests for the Tac-tx bullets if you can fit it in sometime!!!
I'm sure I'll catch flack from the 300blk club but I have no need to shoot subsonic. So I went the route of a 300 Ham'r build as I want to run 150 grain SST and Speer 150s. Even down to the Sierra 125 gamechangers with Wilson Combat's unique twist rate. I was able to harvest 4 does in 2021 out to 250 yards. Great expansion results. It kills but it doesn't Overkill.
Nice you know how to lob them in with hold over. I myself find it foolish to deal with hold overs in deer hunting situations. I limit the 300 black out to 125 to 150 yards point blank tops. It's always best to shoot a rifle of point-blank capability for your maximum shot range. I have lots of rifles and lots of choices but point blank will get the deer all of the time with zero mental errors in hold over.
One of my favorite range loads is a 150 grain Core-Lokt with 16.8 grains of IMR 4227... Not sure velocities, but it's accurate enough and runs well. It's an inexpensive load as I got the bullets cheap a long time ago. My 110 grain TAC-TX load is 18.5 grains of 300-MP. I'm getting 2250 FPS and MOA accuracy with a red dot... 16" barrel for both!
I get really accurate rounds loading those Core-Lokts. The challenge is to get expansion with the lower velocity of 300 BO, which is the purpose of the special Speer bullets.
When I 1st got into thermal hog hunting and suppressors I naturally started playing with 300 Blackout. I've owned uppers from 7.5 to 16 inch and I loved how quiet it was and carrying a SBR around all night is nice because they're lite but I started losing hogs a lot especially once they got out there over 100 yards or when I was using subsonic ammo even at closer ranges. All the guys I hunted with went through the 300 Blackout phase but they all went back to their AR's chambered in things like 6.5 Grendel or 6.8SPC. But we also hunt for landowners on farms and ranches so we need to kill hogs every chance we get and the 300 Blackout limited us to the shorter ranges. Not to mention if a hog runs a couple hundred yards at night you'll never find them and that meant we we're littering the properties with dead hogs instead of us hauling them off to the bone yards like the landowners wanted us to do. I'd love to see what that Blackout Gold Dot will do out of a 308 even at normal velocities to see if they hold together... Great video as always keepem coming brother!!!
@@extractandeject6934 I didn't I honestly just got tired of messing with it and I wasn't reloading for 300 Blackout. It's not a bad cartridge and if you know it's limits it'll get the job done but I was shooting AR15's in 223, 6.5 Grendel and 7.62×39mm. I even hunted pretty regularly with an AR10 in 6.5 Creedmoor so I was use to having a lot more range and better bullet performance. I might give it a try again in the future because I really wanted to like it but for what I do there's better options...
Great work. I've been working up a load for hornady 110gr v-max using 19gr of hodgdon h110. Shooting these supersonic out of a 8.5" ar pistol. Hopefully there won't be to much unburnt powder and it will cycle consistantly.
I actually emailed Speer about the lowest velocity at which those bullets will reliably expand, and IIRC the guy said something like 1200-1300 fps. I bought a box back when you still could and planned on using not only in my 300 BO but my .308 AR pistol with a 10" barrel.
I used 150 gr gold dots for my 8.5" 300 BO and it was one of the more accurate bullets if have used. They are just expensive, but that was the only downside.
Got some of these for 7.62x40WT a couple years back. I’ve had to guesstimate load data for CFEblk since I can’t find 1680 or data for it (not even from hodgdon or Wilson combat😐), but you can get a healthy bump in velocity over blackout. plus the slower twist and tighter chamber / throat “super optimized” barrel absolutely stacks them in. Should be getting 2,400-2,500 fps with a compressed max charge with the 125 grain TNT’s, not 100% on the 150’s but I’d guess 2,000-2,100 fps with more or less 100% fill/ max. These gold dots grouped really well but I don’t have terminated performance data yet.
we'll all miss you johnny, I'm not one of your Patrion supporter's but I will be if you're not quitting. but I have a feeling you are, can't say I blame you with all RU-vid's shenanigans. Hope you have good one man
I’ve been waiting to see the round nose bullets like the interlock get tested for years now lol. Also for the sake of tests, I’d strongly recommend getting a 1:7 twist barrel for the heavier bullets. Noticed some of the old videos with the Lehighs and makers for example having slight wobble. No expert here, but gotta think a 1:7 (that isn’t a silly carbine gas!) would be perfect for that
I vote for trying to get more velocity from the blackout with another powder and see how these do. For some reason, across the board, I have seen best accuracy with my blackout using Winchester small rifle primers
Definitely a reduced load 308 is a great option. I would think that it would be a good hog bullet still. Maybe just maybe a home defense in a rural setting for all kinds of 2 & 4 legged critters. Not a failure for sure.
If those blocks strong coffee color, I must be drinking crude oil. I was hoping those would open more at slower speeds. I vote you ramp them up with h110. I’d be a little leary of those in 30-30 with that meplat though, at least in tube 30-30.
We need more cameras. Scope cam, over the shoulder cam, drone cam, chicken cam

For labradar you need to set velocities to handgun for subsonics. Could be the issue. Also I recommend getting the recoil trigger for the labradar as suppressed subs can be awkward for it to trigger on. Edit after watching more I see you figured it out ;)
I would love to see these in a light load 308, but also at full velocity to see how far she can stretch out in ballistics gel. Also if you could try some 168 grain gold dots in the 308 that would be cool.
Thanks for using Accurate-9. I have been interested to see how it works on 300blk. I am also using the same barrel as you did, so this video is VERY helpful.
Speer's online data shows that you can get up to 2150 fps with Lil' Gun. This would stay above 1700 fps until about 275 yards. I'm not sure what barrel length Speer's data is with and I know a lot of people don't like Lil' Gun in .300BO, but might be worth a try.
I just loaded a bunch of these bullets last Friday to do the same test in my new jell block's. You beet me to it I loaded them in 300 blk. 308 win. and 300 wsm. Now I'm kinda thinking I'm wasting bullets. Good video a little disappointed with the result. I thought they would mushroom better at lower velocity
Looks like a little more load work up. I tend to run in .2 increments until I Find a node. Then I do the odd numbers on ether side. While there may be multiple nodes I tend to grab the best group. If 2-3 groups are similar I load to the lower node to conserve powder and barrel. Just my weird tweek.
Would definitely be interested in seeing the blackout bullet loaded at a “light” 308 and even a full velocity 308 shot into gel. May be a great 308 hunting bullet with massive expansion.
It will explode, its not made for those velocities. In that regard its hardly any diffrent from any other lead bullet in same weight. It wont expand past a certain ammount. What you will loose is terminal performance, to much energy will be lost in the beginning. Just use the 168 wich is designed for the 308.. I would not want to eat the meat you use this on 3000fps or whatever velocity you use it on. And for varmint, thin skinned animals, you really want something with a ballistic tip or hollow point.
@@jmkhenka I don’t think the expansion in this test was anywhere near the point of coming apart. I use the 62 gold dot in 22-250 and it holds together even at those velocities. Besides even full throttle 308 isn’t likely to get a 150 over 3000 fps.
So it would act like a much heavier Speer TNT round, of which the 30cal is something like 120 or 125. Personally I would have preferred to see the BLK Gold Dot to be in the 115-125 (or both options) weights. I’m sure Speer tested those weights but I just think the caliber performs better at 115-125.
@JohnnysReloadingBench My first 300 BO was Hornaday 150 FMJBT BR4 ACC 1680 @18.0 to 19.2 grns .4 steps gave me 10 shot groups in the sub 1 inch, SDs were crap but I found I had the die set wrong and had no crimp this was my first ever load 16" barrel unsupressed ( Illinois has stupid bans No SBRs or suppressors ) they make a near identical HPBT and SPBT
I've had great luck with Ramshot Enforcer using almost any jacketed bullet between 145 and 165 grains. It sucks with lead or lighter bullets. Give it a try!
110 Varmageddon, 125 NosBT, and anything 220 is all mine get to eat. I dont bother with the mid weight stuff - still, great video and info! Also specifically use W296 = u taught me well early on...
OK, I'm a fan and I've watched your channel for some time now, however I would like to ask a question. I have an unfired Armalite AR10T with a 24" stainless factory barrel in 308 that I would like to shoot as well as some of your efforts. I have a batch of Tubbs break-in bullets and I will follow the instructions, 10 rounds followed by cleaning, x5. After that where would you suggest I start to develop a "go to load"? It would be nice to get groups in the sub 1" @ 100 yards as you seem to do with regularity. Do you think it is attainable with a factory barrel? Thanks
Yeah, the cold will really suck the battery life out of iPads and the like. To help out with that you can tape some chemical hand warmers to the back of it or set it down on a blanket with some hand warmers in it. Anything to keep the battery warmer. Power banks don't help much because they use the same battery chemistry. Li-ion and Li-Po batteries really suck in the cold.
Still looking forward to seeing the 62 gr golddot in the .22-250. Curious what velocity will be capable, if it will stabilize, and I bet the gold dot will be up to the task of holding together. Maybe a good deer load for the caliber.
Barnes Tactical 110 grain bullets are pricey, but you can't do better. Lil Gun powder is hard to beat with that combo as well. And do use a competition seating die. Standard seating dies suck. Been there and done that.
Good test. I know you were going for the 150gn but I’ve loved the 125gn TNTs in my 9.5” and 16” blackout barrels. Would have liked to see that side by side with these in terms of expansion.
Yeah.....I really wish he did a side-by-side with the TNT's rather than the Hot Cores. Just sayin. My "hot" go to gound for the 300bo is the 125gr tnt.
Hello Johnny my question is not related to this video, but about anyone of your videos where you check your reloaded rounds in your AR receivers seeing if they will cycle. Do you remove the ejector spring from the bolt when you do this? Thank You.
If you do 308 light loads, H4895 has instructions for, I think, 70% max loads. I've done them for just fun messing around in other calibers, and even 2200 fps is fun on paper or steel; targets don't have to be punched at 2750 fps. I think a low power 308 would be a fantastic youth load.
Im really curious if the 300 BLK-OUT version would do at 308 velocities. Would it frag. or mushroom amazingly well. You really need the Lee ball cutter and a case prep station. Easier on the hands. Can you work in some more K31 content?
The nutcracker style bullet puller in the back - testing it? My hunting partner always uses 150 grain factory SP bullets in his 300 BO pistol for deer hunting under 150 yards. We have never had to look for one. Great results.
Nice! New 300 blackout video. I’ve watched probably 40-50 of your videos. Is there a reason why you don’t use a progressive? If you’ve mentioned it before I may not have seen the answer. Thanks for the answer and your time making these videos.
! would love to see someone gel test a 30/30 bullet from 300blk, seems like it would perform much better given the velocities involved. A larger meplat should help a lot. Also, I feel like your groups would shrink if you Lee Factory Crimp Die those loads... Would be interesting if you took the worst group and did ten plain and ten crimped.
Some good testing jrb . Something I was hoping you where going to test. makes me wounder about that bullet know Actually looking for them to try in my 16 inch gun. Wonder how they do at faster fps with h110 or 296 in gell or groups. Definitely think in a 3030 bolt gun or single shot they would do well . Maybe a down loaded 308 for kids maybe lot to play with.
The 150GD is an odd weight. Speer makes a 123gr .310 for AKs. Would be interested to see you try some out in 300blk, either resized or just loaded and see what they do. Also the GDs are duty type projectiles rather than hunting oriented. They do really well against barriers and vehicle glass.
I wouldn't try it. It's a couple thousandths larger then the .308 for blackout. Doesn't sound like much but it increases the chances of a bullet stuck in the barrel. If not, performance would be severely effected. Plus the there's 120, 125gr loads in blackout too
I dont know as much as someone else. But if I'm not mistaken 300blk out barrels are commonly made for heavy bullets. Maybe if you had a slower twist rate it could improve at least the accuracy. As for mushrooming something like the 30-30 or 7.62x39 may provide better capabilities.
Idk, my 16inch 1n8 twist 300blackout is damn near doing single holes with 125gr PPU FMJ. 3 holes touching at 100yrds. As for the barrels they tend to pick twist rates that work for both subs and supers....which is why you commonly see 1n8 or 1n7. 1n5 exists too in a 5inch barrel. 7.62x39 bullets are too big at .310 diameter. 300blackout uses .308 projectiles. Loading .310s would have negative impact on performance or worse you get bullets stuck in the barrel if they even chamber
Based on this I got no use for 150’s in the 300. If you’re taking requests midway has 125 tipped gamechanger factory seconds. I was told by Sierra they would expand well down to 1700 ft/sec.
I'm kinda "meh" on the 150 GD for BLK. Tried them out of my 10.5" pistol. Got decent accuracy, but when I ran the numbers, the 110 TAC-TX at 2350 has more energy and much better expansion. So I'm sticking with the Barnes for now. Not sure what to do with my other box of GDs... Sounds familiar...
Same here. Anything over 120 gr you start losing too much powder capacity on top of trying to push a heavier projectile. If you go any heavier, might as well just use subs.
Where did you get them? I can't find them anywhere. These are fantastic on whitetail deer. I use Lil gun and the expansion was great on the animal I was able to recover the bullet from. My longest distance is 150 yards and have taken deer at 50 to 65 yards none ran further than 25 yards. I don't think it would be good much further than 150. 1.5" group at 100 yards with my load and that seems standard for my barrel
Looking at speers loaded ammo, they shows a muzzle velocity of 1900fps and a velocity of about 1675 at 100yds. Using speers data with accurate 1680 i was able to get up to 1982fps at max.l out of a psa 16in upper.
Not sure if you are interested, I use Enforcer with my 150's and they fly WAY better than W296 in terms of accuracy and velocity. Would be kinda cool to see you have a face off with those two???
You didn't mention it, but where most of the Hotcores penciling straight through the gel? I saw only one recovered, but when watching the gel, it looked like several bullets passed through.
It would be interesting to see what the expansion would be if it was loaded closer to factory loaded velocity. Looking at Sierra data for 150gr projectiles I think an H110 or CFEBLK load would get you to 1900FPS or better
Don't you typically measure the 1st few resized cases with a case gauge to determine how the resizing is going...? I've found it can save a lot of extra work later on. P.S. What about using small rifle magnum primers for 300 BLK: I've seen quite a few listed in various load data sources...?
