Reloading .38's question

Any reason to case trim 38's if being fired from a Puma 92?

Most likely no. Straight wall pistol cases actually tend to shorten a bit as you reload them. At least, that's what I've observed...

If you want to know for sure, just measure them from time to time.

I have been loading .45 Colt and .38spl for a while now and have never trimmed a case. I have also had NO problems.

Ditto.

Never trimed any of my 38's as well.

The one reason you might consider trimming is if you take advantage all the discarded 38's you find at a public range and you end up with a batch of cases with slightly different lengths. Loads that you crimp should be real close to the same length because about the largest velocity variation you'll find is from crimped loads where the crimps are of different depths.

That describes my 38 case situation and I sorted by brand and then did a little trimming and have never purchased a 38 case.

When I load for my Braziltech (sp) Rossi .357 Mag , I seat the bullet 1 groove further out / longer with .38 Special brass . This gives ~ the same OAL as .357 Mag . I use the same ~ 150 grain Lee RNL bullet and powder charge for both kinds of brass .

And , no , I have never trimmed handgun brass or .45-70 brass .

God bless

I guess I'm the exception here - I trim all of my brass exept
45 ACP, 9mm, and like that. Most of the 38 stuff I've loaded
has been for target work, and Lord knows I need all the help there
I can get - hence the careful case trimming crimping.

Trimming is about my least favorite realoding step. I really
don't care for it, but I think it helps with accuracy.
