I shot a regular 6.5 grendel AR space gun last year. 28" barrel. Ended up using the 107 non tipped matchking with a stout load of benchmark. 2825 fps. I could get 2875 but was a brass killer. Tried 80208, tax, h335, and a few others but benchmark was the most accurate. Wanted to try some of the power pro stuff but never did. Lever evolution did good with the 130 vld but shot better groups with the 107 so I used it for all courses of fire. 200-600 yards.
I run a 105gr MKZ over a stout charge of n530 in a 24" upper from Sanders armory and get a little over 2800 fps out of it. Groups normally hover around 1/2 moa, but sometimes get closer to 1/4. I'm using hornady brass, and get a fair number of fliers that open groups up to 3/4. 123gr factory ammo generally gives 3/4 at 2600. 123gr reloads over 8208 runs 2500, but stays 1/2 or under.
Have almost the exact same groupings on my targets in the basement but from a BA 20" SS fluted barrel. 28.5gr of 8208 XBR over 123gr SMKs and let it fly.
You’ll hate to hear this but carbon wrapped barrels are only good until they heat up. The bonding and the carbon start to fluctuate severely. I’ve tested these barrels extensively and they’re not worth the money. My Bartlein 6.5G puts most rounds into .4’s to .7’s. 107gr TMK with 28.5gr 8208 XBR at 2.260” (2650 fps) and 100gr ELDM with 32.5gr CFE223 at 2.245” (2750 fps). Do Satterlee’s 10 shot load development test and you’ll save a ton and really find out what works.
Slowly putting together a Grendel myself. From a lot of my research 28.5 of XBR seems to be THE load for the 123gr bullets. This rifle is going to be mine but it will be used by my son to shoot the PBR monthly matches over there at West End once it is together and he gets some trigger time with it. Beautiful rifle and nice shooting.
I'm taking the H335 out for a walk tomorrow with the hornady 120g eld match. I'm going to shoot 100 reloads at different gr's till I find the best standard deviation and groups. Since you seem to like the xbr, I'll pick some up tomorrow and try it out . Using the BC 24" fluted heavy barrel on my Colt 6920. Will warm up with 40 rounds of the Hornady black box 123 gr eld match.
Curious on the load specs. Jump, coal, oal, brass. On my barrel, the longest oal I could do is 2.292" due to mag limitations and this was .05 off the lands. Single shot/manual chambering, I could go out to 2.30 just off the lands. This with the 123gr ELDMs. With the 120gr ELDMs, I can go to 2.290 and just be .014 off the lands. SSTs were close to the ELDMs. Great Video!
Very nice. I don't reload and have tried 3 types of factory ammo and so far the Federal Fusion shot best. Hornady Black was terrible and Wolf was OK. Weather sucks so I didn't get any shooting in this weekend
You definitely had some nice groups, one thing nice about reloading so many things can be tweaked. Good to see you taking that mother out to the range.
Hi John. I had to take advantage of being first...now back to the video... when I shot competition matches while in the Army I learned how much of a sciences shooting is. So much of it is balancing skills and managing the available production of powder and related items to make a bullet. In the 80's a competition round was one dollar per round. Now I can bet it would be more unless you load your own. Nice to see you out at the range.
that right for sure... SCIENCE !!! the bullets are what gets ya... these are about 35 cents a piece. prolly about 70 cents to make each one. but now I have a couple winners to choose from. thanks for the comment brother, always good to see ya here.
My 6.5 Grendel build, I installed a 24” barrel (M) Deadshot Barrel out of Oregon. I started with powders CFE223 AND 2520. I selected these powders to use in the 223 Remington cartridge. I did find out that starting at 28.5 grains would not operate BCG, so I stepped up things to 30.5 both powders 2520 the better powder but both producing almost the same velocity with the edge going to 2520.
123gr ELDM, TAC 27.0gr I got 2011fps with 3.1 SD. my barrel is not as long as yours however. 27.3gr TAC got 2033fps, with 10.4 SD. Temp was 55deg F @ ~1000ft elevation
You did have some places to explore a bit more... shame bout the Tac being so slow. H335 has the speed but has too much pressure... can't wait to see how mine does.
yea exactly... I think i can work with the TAC... dont recall if they were compressed or not... im optimistic. Looking forward to your results as well man, your are good at what you do !
I know this is an older video. What COAL are you using? Which primer? What brand of brass? I’m just getting started with 6.5G. Been loading 5.56 for a year and a half now. Thanks for making good content!
Do you guys clean your rifle when switching powders? I shoot rl-15 then switch to BLC2 for the big 85gr bullets in highpower competition. I had a couple people tell me not to switch powders during a match. I've been shooting a long time and never saw a problem.
CFE223 tends to perform better in my 6.5G when the case is closer to full. I should try magnum primers and see if it helps. I also tried TAC, and it performed well, but I saw slow velocities with the load data ranges i was given. Which range do you go to?
Im loving this little mamma Jamma ! cant wait to take it out to distance now that I have a good starting point for my precision load work up ! im gonna make a 1000 yard scalpel outa this gun !!!
What did you call that rifle? The "Mother of All Grandmas"! What? 😇 Your range looks like it's in the Baja desert....oh....wait... Glad you had a great time!
@@WTFSoCal - All I'm saying is that you should take emergency water & rations with you every time you go downrange to change your targets. lmao!!! BTW, isn't Grendel a children's story character? Hansel & Grendel? ??
@@WTFSoCal I thought it looked like it but I was not sure....I like going to the private ranges there but you have to have somebody with full membership....thanks for getting back to me....
Could you send me some data just started up loading not had as much luck as you with recipes factory has done better but only as good as your worst group I got a 18" stainless barrel at 200 yards trying to get those groups at 200. Looking to cook up some high fps can be high recoil very flat long range hunting load for white tail Thanks!
California is my birth state; I was raised in the LA/Compton areas; I lived there until I joined the Army in 1968. What is happening in California these days with all that is going on? I built an AR-15 in 6.5 Grendel; it is a shooter, period.
