22-243 Winchester loads

[MerlinMc]

I have been using 48 gr of RL25 behind 75 gr Hornsby ELD-M. Barrel is 28" with a 7.7 twist.

Any ideas on loads using a more temperature stable powder that would perform similarly to the RL25?

Thanks.

I'm shooting a 22-243 I'm using h4831sc, rl23 might be another good one to try. I'm shooting the 75gamax too. my load is getting 3500 using Winchester brass fed210m primers 26" barrel. My cousin had a 22-243ai he is using rl23 with the 77tmk. Both our loads shoot big holes. His is a little faster right around 3600.

Thanks! How many grains of H4831 are you using?

43.5 is where I settled in but work up to that

In my 22-243 I'm running 44.5 RE23 under an 82gr Berger LR. Velocity is 3,450.

When I was shooting the AI varient I was loading RE22 under a 75gr A-Max moly bullet for 3,670 ft/sec with incredible accuracy.

What is your 7828ssc load? Thanks.

If it helps - I used 47.0gr H1000 under an 80gr A-Max bullet. Velocity was 3,360 ft/sec. Accuracy was very good with groups just over 1" @ 300yds. I assume that you could work up to achieve more velocity if needed.
