I'm experimenting with reloading using HP-38 that I have for other calibers, but the loads I've come across are all over the map. I'm using Hornady hollow point (85 gr, from memory) bullets. Anyone have any favorite recipes? I also want to try Hornady 100 gr semi-jacketed. Any advice on that?
Thanks for the reply. I'm using .308 and .309 commercial bullets. The initial 4+ gr (Hodgdon recommended) loads I first tried were too light, so I'm in the 5 gr+ range now, and walking up slowly. The Lee recommended loads (included with the die set) are for a powder I'm not familiar with. If I get ambitious (and caffeine overloaded) I may try to extrapolate pressure from published data, but I doubt that will happen soon. I have the feeling PPU loads their rounds hot, but again it's subjective. I may break down a couple of their rounds and see what their load is.
I haven't tried the new loads at the range yet, but I'll post results as I go along in the hope it might help someone else.
I finally got to the range. My Tok seemed happiest with 5.1 gr of HP-38 with an 85 gr FMJ. I also tried 5.5 gr and noticed no real difference. There were a couple of FTF problems with JHP: I need to refine my seating depth/OAL and try again. Brass was a mix of new Starline and mixed commercial once fired. CCI primers.
Decent recoil; fairly accurate. Doesn't "slam" the slide like PPU and RAS (the recoil spring is stock). I have some 100 gr bullets I want to try next time as well. I'll update after the next test round.
Of course, any advice would be appreciated at this stage.
I also installed an aftermarket hard rubber grip I bought on Ebay for ~$30. It improved pointing characteristics noticeably. I fired 75 rds of PPU without incident, but I noticed one very hot round (large fireball visible in daylight). THAT's why I handload as a rule.
Next range trip/load experiment to come soon, with report. BTW, I now refer to the M57 as my "fun gun" - she attracts a lot of favorable attention at the range.
