bandw1dth Posted September 19, 2017 Share Posted September 19, 2017 Who here trims pistol brass? Or even checks the case length? I never have and I primarily load mixed brass. Should I be checking the length? Link to comment Share on other sites More sharing options...
9x45 Posted September 19, 2017 Share Posted September 19, 2017 Not needed, and I have never done it in over 45 years of reloading. Now rifle, that is different. Link to comment Share on other sites More sharing options...

Hi-Power Jack Posted September 19, 2017 Share Posted September 19, 2017 Not only do I NOT trim, I will load anything I can get the primer out of, and isn't cracked Link to comment Share on other sites More sharing options...
RaylanGivens Posted September 19, 2017 Share Posted September 19, 2017 I use a hundo case checking gauge... After checking 100 rounds, I turn it on edge and look down the flat surface to check the primers... Sometimes I'll notice a case or two that sits a little higher... I used to pull them and use them for practice... Never had any problems shooting them, so now I just shoot them. Link to comment Share on other sites More sharing options...
DukeEB Posted September 19, 2017 Share Posted September 19, 2017 From what I have read, pistol brass shrinks instead of lengthening. how many times can you reload 45 brass? Link to comment Share on other sites More sharing options...

R1_Demon Posted September 20, 2017 Share Posted September 20, 2017 I asked this very same thing when I first started reloading 40 earlier this year and that is the answers I got. Nope, unless you are shooting rifle. Then yes, you would want to check it and possibly (more than likely) trim it. But for pistol, no, it isn't necessary. So, I never even bought the trimming equipment until I'm getting ready to load for my .308. ;-) Link to comment Share on other sites More sharing options...

deerassassin22 Posted September 21, 2017 Share Posted September 21, 2017 I trim about 500rnds for my 9mm 929 gives me more consistent lengths and chronograph results but then again I never loose my brass. Link to comment Share on other sites More sharing options...
noylj Posted September 21, 2017 Share Posted September 21, 2017 If the case head-spaces on the case mouth, then trimming just increases head space and leads to worse accuracy. Pistols already start off with excessive head space from all cases being too short and it just gets worse. Many Bullseye shooters who shot .38 Super only loaded a case three times, as by then it would have shrunk enough to upset accuracy. Bottleneck cases grow because their is a SHOULDER pushing forward while the base is being pushed back. No shoulder, no stretching—though I have been told that hot .45-70 loads can grow.

noylj Posted September 21, 2017 Share Posted September 21, 2017 Deerassassin22: Did you verify the ACCURACY improved? As long as you are head spacing on the rim (moon clip?), it won't hurt. I tried with .38 Spl, .357 Mag, and .44 Mag and saw NO improvement in accuracy out to 50 yards, and consistent velocity does not equal better accuracy in a handgun at 50 yards or less for any gun I have owned.

deerassassin22 Posted September 22, 2017 Share Posted September 22, 2017 (edited) I was just more concerned with chrono results so I could load closer to PF. One day I could test accuracy but I don’t have a home range yet Edited September 22, 2017 by deerassassin22 Link to comment Share on other sites More sharing options...
