Several years ago I shortened a few thousand Starline 38 Long Colt to 38 Super length for a true rimmed 38 Super.
At the time 8 shot 38 Super revolvers were stupid expensive and hard to find. And the bullet I was using didnt get along well with 38 Short Colt brass. So I ordered a 38 Special trim die from CH4D for the Dillon trimmer, shortened it by .310 and got to work. It worked well and it went fast. The trimmed brass was 100% functional, but it was not as good as I had wanted. Then in 2014-2015 Smith came out with the 929, an 8 shot 9mm revo. My 627s got pushed to the back of the safe.
Fast forward to now... I decided to load up some 38 Special +P+ ammo for my old 5 inch Smith 38/44 Heavy Duty which is basically 38 Special in a 44 mag frame. I decided to trim all my Starline +P brass to the same OAL because they were off by 4-5 thou. I broke out the Henderson trimmer and now they were all to within .001 of each other and have a nice chamfer and deburr. You cant do short calibers like this on a Giraud trimmer. Anything shorter than 223 sucks and anything shorter than 300 Whisper/Blackout wont work.
Then I remembered my 38 Shemedium brass. I got to work on it last night. Soon all of it will be better and the little OCD twinge wont flare up when I think about shooting my 627s.
The bad part is that because this Henderson idea is working so well, now I have to do 500 pcs of new 454 brass and 500 pcs of 41 Mag brass.
