25 cal 134 Eld-M vs 133 Berger EH

This is totally doable, in lapua brass I never found pressure with 131s and rl26 till around 3100mv from a 25in barrel

Rl26 will add 150+fps over H4350.

Agree, and I believe @willfrye027 gets 2900+ without pushing pressure with the 134 ELDM in a 26" CM.

Previous barrel was 26”, n555 pushing the 135s 2930fps with lapua brass. Some pieces are up to 10 firings without a lost primer pocket.

Current barrel with 134s is 26” with h4350 doing 2850ish in alpha brass. Can be pushed a little faster than that but was getting an occasional heavy bolt with long strings in hot weather so I toned it down a little.

Thank you and if a guy has some unobtainium RL-26, 3,000 is likely pretty reasonable in a 26".

You can probably do it with normal powders and be over pressure. The 131s IIRC have a shorter bearing surface and can be pushed a little faster than the 135/134s
