Need load for 143eldx & rl26 or something powder? H4350 not good in 264 WM I guess. Been loading retumbo 68gn 129 sp. 1/4" @100. Seem like 143 eldx hellova bullet for mule deer n elk. I just need to find what my mod 70 needs to push it. 3100-3150 fps is all I'd like. Got on hand some varget, h4831, H4350, superformance, retumbo, imr4350. Rl 17, rl22 & rl26. Thanks. Happy shootingWhat barrel did you end up going with for your 264 WM? I got my 264 back with the Badger Thruster muzzle brake, but haven't had it out. Not that it "needed" a brake, just wanted it. Lately I've Been too busy with the 338 LM, the 308 Win, etc. Plus, it's heating up in my neck of the woods, almost time to start reloading for summer, switch to pistols and indoor ranges, LOL!
I think you have the data I got with my 264 and 143ELDX/RL26.
Let me know if you want me to put it here for you.
