Reloading the 357mag

[skeet]

Allen..With Commercial brass i doubt it would make a big difference. With Rifle ammo many rounds were based with military brass which was usually heavier..but as Jack said.. it surely can't hurt and you only have to try a few 10ths less. I also would drop back. with the pressures you are looking at..may make a big difference. When loading 45 auto 38 spec and other rounds I load 'em mid range so mixed brass is not a real big deal...with magnum stuff I weigh every powder charge when loading at the max. with a RCBS Chargemaster electronic powder measure scale combo. Same with rifle loads.. I am a chicken in my older years
