RL22, H4831SC, IMR7828ssc. RL22 has proven to be temp sensitive for me but was clearly the fastest

Re: Powders for 243 Winchester w/105 AMAX
IMR 4350 works great for 95gr or 105 gr bullets. Around 42-44gr is the load i use with wolf primers. I consistently get 1/4 and 3/8 groups at 100 yards.

Any chance you are shooting the stock Remy? If so, I am doing the same thing. Trying to burn out the barrel before changing to a new one for my son. The best powder I found for that pill was the Vhitavourhi N550. It was definitely sub MOA. When I couldn't find N550, it was a bitch to work up the load and the speed that I was looking for. I have tried, H414, RL15, 17, 22, 25. All didn't have the same result as the N550. When I get to Retumbo, it was very close in terms of performance, although still a bit slower thant the N550, but certainly it was in the ball park. That's what I have been using. Good luck

Have a 243 rem 700 24" 1:9 1/8. shooting a short line accuracy node load 105g amax with H4831sc 39.5g. Distance load 45g same 4831sc. It's consistent, not temp sensitive that I can tell.

Re: Powders for 243 Winchester w/105 AMAX
Thanks to all... I think I'll work with 4831SC for a while. I had pretty good luck with it and 95 gr. VLDs... pushed some 107 SMK with some success too. I just don't think the 1in9 will work for the 107SMK at long range, although I did get a sub 1/2 MOA group at 100 with 42.0 4831SC...
I'll post results with the 105 Alpha Max and 4831SC in a few weeks for you guys... thanks again.

Re: Powders for 243 Winchester w/105 AMAX
IMR 4064 works for me, but I have used IMR 4350 with good results. Going to try the 4831sc.
I am willing to learn.

Since you use BN coated in the 115's do you see an issue when switching to non-coated bullets?
Curious about switching from BN to bare if accuracy changes or if you do anything special when changing to non coated

Re: Powders for 243 Winchester w/105 AMAX
switching from hbn coated to non coated will increase pressure somewhat. quickload showed about 50psi iirc. ymmv

Re: Powders for 243 Winchester w/105 AMAX
My 243 loves RL-22 and 105amax's but i haven't tried it in anything but temps of 80-90 deg.

Re: Powders for 243 Winchester w/105 AMAX
Ditto on Retumbo... I'm shooting it with the 105 A-Max's in a factory 700VS. Accuracy is the the 1/2 to 3/4 MOA range. Should end up somewhere in the 47-49gr range and in the mid 2900's or better.

Don't have the data in front of me, but the range for the Retumbo sounds about right if you want to push beyond 2900 fps.

48.5 grains is what Dan Newberry is recommending as an OCW recipe.

RL 22 and Ramshot Hunter have given me very good groups. I am shooting 105 Bergers.....

Re: Powders for 243 Winchester w/105 AMAX
OK, as is promised I've done some shooting with H4831 SC and a few 105 AMAX. The few that I could find. Results were good around 2900 fps at 400 yds plus ranges in my 1-9 Twist Douglas Airgauged barrel. I'm shooting a 22" bbl. Longer ones should easily produce over 3000 ft if needed but 2850 to 2900 seemed to be the magic number in my gun.
I give up trying to find 105 Amax bullets. My barrel is about done anyway so I'm rebarreling very soon. I'm going to concentrate on shooting 107 SMK, 105gr and 108gr Bergers.
Anyone got experience with these bullets? I'm looking for a twist rate recommendation. I'm thinking 1 in 8" because of availablity of barrels but also thinging 1 in 7.5.
Any thoughts?
