Being new to the revolver game, is trimming 38 spcl brass something to be considered?
I was wondering due to the case being roll crimped, resized, flared and crimped again.

Also is there something I should be on the look out for that will say "Time to replace me"?

Because I only shoot paper and use light loads, I taper crimp instead or roll crimp.  The cases will start to crack at the neck, that's how you tell if their done.

Few reloaders trim straight-walled pistol brass.

Thanks for the replies.

Revolvers are a new platform for me.

I got a large supply of mixed 38 brass from my dad. Sorting thru it I found the lengths were all over the place, and not brand dependent. Wasn't able to trim them with my 'rifle' tools, so I got one of the Lee press mount units. Had to modify it a bit to trim the shortest ones in the bunch.

They're loaded. May just put them back in the tobacco tin and tattered boxes they came in after I shoot them. No reason for doing all this other than nostalgia. He'd take me to Coyote Point to shoot my 22 when I was a kid, and then I'd sit on the bench and watch him shoot his K-38.

I shot a DR match with it awhile back.

Trimming 38 SPCL brass Empty .38 Spl case trim

IF you are roll crimping, having cases the same length will be helpful in obtaining uniform cartridge production.  Otherwise- not necessarily.

I am roll crimping. Making the cases the same length for a uniform crimp makes sense.
I have to believe that roll crimps create more stress on the case mouth than taper crimps.

I'll need to mic. a few and see if there is some lengthening of the case after two-three reloads.
