Good info, do you have numbers from a 4.75" or 5" barrel?

Thanks for the info! I've got a 4lb party keg of AutoComp on the shelf I've been wondering what to do with.

No I dont. I just loaded for my 10mm hunter. Sorry just getting back. I thought I followed this. Guess not. Haha. I will be loading some a bit shorter for my wife's xd40 but it will have a much shorter OAL. I have some 38 super data from the same load 4.75 to 6 in barrel. It was a waaaay hot load w a 124 the 4.75 was 1500 avg fps the 6in was 1588-1600fps. So 1.25 longer barrel gave me 80-100fps more. The stock stuff I had claimed 1100fps and my gun was in the 1170-1180s hope that helps.

Again I loaded waaaay long for my 10mm barrel. Used a 10mm OAL. Or near it.

I really enjoy this stuff. It's really strong but really slow? Side by side w 3n38 the 3n38 was softer but the autocomp at the same pf was almost flatter w the comp I was using. It was snappy but. Really really flat
