I really don’t want to hear the “I’ve never trimmed pistol brass” comments but I do have a question. After reading several topics about trimming .357 cases, quite a few people are talking about trimming after they resize and flare the cases. After resizing I understand but after flaring seems wrong. Wouldn’t that normally be done before flaring if it’s done at all? I can’t think of a good reason to flare first. | ||

If I were to trim pistol brass, it would be after decapping and sizing the brass. Getting shot is no achievement. Hitting your enemy is. NRA Endowment Member . NRA instructor | |||

Never in 30+ years of reloading, but to answer the question, any trimming should be done after resizing and before flaring.

As posted above. A while back I couldn’t find any 41 mag brass, but I could get brand new 414 mag Starline brass. It’s pretty much the same, about 1/4” longer. I set up to trim back to regular 41 mag length, took a while, but worked fine. I left a few a little long, for snake-shot loads. | |||

I am in the trim before flare camp. Flaring first could be inconsistent due to different case lengths. Then you would remove different amounts of flare based on case lengths before trim. | |||

Resize, trim, and then neck size works well for me. As long as the cases get trimmed the same length, that's all that matters. I trim to 1.280" because the cannelure on one of the bullets I load will make the loaded cartridge longer than 1.590" if the brass is any longer than 1.280". | |||

When I reloaded 357SIG I Deprimed Cleaned Sized Trimmed Primed Expanded Powder Seating/crimping I quit reloading for the caliber and bought a 40 barrel for my duty gun and just shoot 40 "Violence, naked force, has settled more issues in history than has any other factor.” Robert A.

To go a step further from above post, if you trim after flaring the mouth and then get inconsistent amount of flaring, you will also get an inconsistent amount of crimp thereby having a detrimental effect on accuracy. | |||

^^^ This right here. There’s no circumstance where trimming after flaring would be appropriate. Demand not that events should happen as you wish; but wish them to happen as they do happen, and you will go on well. -Epictetus | |||
