Congradulations on bringing target movement into long range hunting, as an ex sniper that has fired thousands of 300 win mag rounds I will never shoot at a moving big game animal period. I currently shoot a 28 Nosler and personally believe its the best big game cartridge up to brown bear with the Nosler 175gr ABLR. The comments of a fast cartridge being a barrel burner is so irrelevant to a hunting rifle that you only verify the zero before each hunt lets me separate the BS commenters from true knowledgeable shooters. Great presentation and I appreciate the cost and effort to bring truth to the shooting public, so thank you.
I assume you are talking about the "Chairpod" product that they have? It appears to have the same swing arm, it's just painted a different color. I would guess that our kit for the 360 Chair would work just fine.
Well, it's relative. I think they both have their pluses and minuses. The Proofs are more money, wrapped carbon fiber, cut rifled barrels and smaller profile/lighter. The X-Calibers are less money, sleeved carbon, button rifled and larger profiles/stiffer/heavier. You have to pick what's right for you. They're both going to shoot good.
So what's the deal with n565. I bought a pound. Thinking it was 165 then when I got home. Realized it's not what I wanted. Now I can't find much about it. Can anyone help maybe ??
N565 is slower burning than N165. Both are great powders. There is pretty extensive load data on the VV website. If they don't have the cartridge you want to load for, use Gordons. Or take the data on the VV website and find a similar size cartridge and bullet weight to what you have and scale the charge accordingly by percentage, charge weight to water capacity.
Great question. I recommend starting load development AFTER you have 100 rounds on the barrel. You can start the load development when the barrel is new, as I did with these rifles, but the velocity WILL migrate, and you need to be prepared to deal with that and not be intimidated/frustrated/discouraged by it.
Hey !!! This email just in from Hornady about their 190 grain CX for .308. "This bullet is going to require a 1-8 twist to stabilize the bullet. So for every chambering that is running this as a standard twist rate we would be updating this bullet into that data. Thanks Hornady/SnapSafe Tech Team" We bought hundreds of these bullets in the last couple of weeks for our Oryx and Elk hunts this Fall with 300 Win Mag. Now what? Where's our money now? Not cheap bullets, now utterly useless. NOWHERE on the Internet does it say anything but normal 1:10 twist. Last Thursday I was printing out their load data for this 190 grain CX for 300 Win Mag. My $$ iPhone app showed the same. Now, poof, the 190 grain is gone! So is our hundreds of dollars we spent on their CX bullets. With just a sudden cold email response from Hornady.
@JohnDavidHays I NEVER go by the manufacturer recommended twist rate. I use the Miller formula. Berger has a stability calculator on their website. You need to know the projectile length and your barrel twist and environmentals. The calculator does the rest. I use sea level and 0 degrees as a baseline. Under those conditions, I want 1.6 stability factor at a minimum. I typically want as tight of a twist as I can possibly get, for everything but 100 and 200yd benchrest. Sorry you got snookered. Typically mono's need/want faster than standard twist rates. I error on the side of over twisting than under twisting.
The spreadsheet that you show with the hit probability is sold gold. Does that come with the Applied Ballistics Analytics program or is that data that you pulled from the software and compiled in one spreadsheet? Also is that the $200 software that I see? Thanks
Thank you! No I made that spreadsheet before we even built the 22 Nosler test rifle. That's why we did the entire project. I figured out that we could duplicate big game hit probabilities out to 600yds with a 22 Nosler. Knowing that we would be doing future series on big game rifles and setting a 600yd ethical limit. That way we can make you a training rifle that you can shoot a lot of volume AND we can make you an identical big game hunting rifle that looks and feels the same as your training rifle. Correct, the AB Analytics Package for $200.
This is how I select a charge weight. Three loads per charge weight. You are talking me into trying N550 for my .22-250. What’s the secret to consistent seating depth. My case length seems to vary .002
@Not-the-only-one right, this is my more involved method I use when I REALLY want to explore thoroughly. N550 and H4350 are optimal for a 22-250 with 75gr or heavier bullets. If you're using traditional lightweight bullets, N133, N135 and N140 would be optimal. Run the handle like you mean it. Don't baby the bullet into place. Seat it fast and hard, all the way to the stop. And measure to the ogive, always. Never the tip.
I have been loading rounds on fired brass without cleaning them and having really good results. Just FL resize w/o mandrel in die. Expanding with mandrel on separate step. Have you ever used this method, and at what point do you anneal your brass?
Didn’t do the ladder test for my .22-250 but it really liked Varget when I started to stand on it, well over max book charge. Im going to start using your method for my load development. What brand barrel chiller do you use? Thanks.
@Not-the-only-one Chamber Chiller with USB for connecting to portable battery packs. Happy to hear you're going to integrate my methods. It's life changing. So much less wasted time and resources.
For new handloader....To your point, I can't believe how many people rely on B.C. for NO REASON. For example, if your hunting in an area where your max distance for a shot is 30 yards from a tree stand, and your shooting white tale with a 30-06, you don't need a 210 gr projectile with a G1 B.C. .600 (.302 G7). Something like a 180 grain Flat base round nose Pro-Hunter with a G1 B.C of .280 is more than sufficient to take your deer. A moderate loading at 2,400 feet per second is more than enough.
@kenthall6584 In order to make the cut for this comparison series, it had to have "long range" factory ammo available. Which = No Wildcats or obscure cartridges.
Nothing you say should piss anybody off. If somebody gets pissed off, they’re just not mature. Not many people show others or share experiences like you do. Free schooling. They can just go somewhere else and don’t leave anything negative. Otherwise they will be doing what you do. Keep on coming with more videos.
Same powders as the .280AI N550, H4350 & N555 You could use N150 as well but it's a little fast for that cartridge. All of the 4831 class powders are too slow. Especially if you are loading to fit in a short action magazine and running the wimpy +P pressures. With a modern gun like that, you can go higher. I built my Roberts on a Remington 700 long action. So, my loaded rounds are over 3" long and I run over 60K PSI with No issues. I'm about 100fps under 25-06 velocities. (I have a 7" twist 28" barrel)
So... half of the videos, the comments were turned off. Which I didn't do. Clearly, as all the videos have comments on them. Which would mean that I would have had to gone into half of the videos one by one and turn the comments off. Which I didn't even know how to do, until I figured it out just now. Which means YT is trying to throttle our channel down.
I was so excited to try and get the software you've been using for this series... especially the Applied Ballistics. Unfortunately, I am a Mac user and they don't work on Mac. Do you know if I could pick up a cheap tablet to use this software? Any experience with it running on a Droid platform? ... or is it Windows running on a leptop only?
Boy you know it when that baby goes off..and everybody within 11 square miles..lol. Dude you got me itchin to start addin goodies to my ol 700 7mag. 1st rifle dad bought me round 99 and been a fan of 7mm ever since. I’ve got Winchester supremes ve had over 20yrs where it on,y takes 1 and absolutely destroys deer lol.. those noslers in em work as good as any bullet I’ve ever landed on game. Ballistic silvertips. Have 155gr terminal accent over 2yrs and havnt fired a 1…lol $3.75rd.👊🏻
Great info. The barrel length data is interesting. I was wondering if adding a suppresser increase muzzle velocity and if the length of the suppressor matters?
I’ve watched each video up until this one. I have a question regarding bullet seating for ladder testing (I apologize if you addressed this and I missed this answer). Since seating depth effects pressure and velocity, how do you decide on bullet seating depths for a ladder test? Do you have a recommended seating depth for a ladder test?
I didn't cover it. Use the Hornady Lock-N-Load tools and modified cases. Those tools give you "Touch". Start .020" shorter than that. No need to go closer. If you end up doing a seating depth test later. You should seat deeper in the case, which will reduce pressure; until the powder is heavily compressed. Then the pressure will skyrocket as you seat deeper and deeper (More heavily compressed). It's a U shaped curve. With Touch at one end and heavily compressed at the other end. But as you get closer than .020", pressure rises very quickly.
This is exactly why I handload. I know exactly what is inside the case, and precision shooting doesn't agree with factory ammunition, and I ain't kidding either!
In part 1 of this series you mentioned seating the bullet out to get extra performance. What C.O.L. are you using with your hand loads in the 7mm rem mag with the 160 cx?
Another great video Tim. I appreciate you sharing your thought process and reasoning with your load development. Im very interested to see how the .280 looks next week.
Love following along on this 7mm series. Thanks for all you do! My biggest take away is to look for the most consistent Avg POI in addition to SD and ES on load work up and don't get sucked in to a group that shot one time tiny but in a different POI, than the rest.
