I've had quite a bit of fun working with the 380 Auto this year. I've been working on two bullets; a "light" bullet for the sub compacts and a "heavy" bullet for the full frame autos. What I've end up with is a 100-grain and a 125-grain bullet, the weight difference dictated by the shorter OAL for the magazine requirements of the subcompacts.
My "test mules" where the Jimenez Arms JA-380 and JA-LC380. Cheap pistols but the important thing for my work is that the chambers are cut exactly to SAAMI specs and their barrels are ballard cut, not polygonal. Once my inital testing was completed, I was able to locate representatives of most frames in circulation and like I said, I've become a believer in this cartridge.
With the TLC358-125-RF and loaded to a NMP of 17.1K PSI, I've been able to exceed the Hatcher Index of 9mm Luger 115-grain FMJ factory ammo.
It's too bad that bullets for this cartridge have been ignored by mold makers but a lot of pistols have been pulled from night stand drawers in light of the OHB inspired "handgun pride". Owners wanted ammo and with the seasonal runs of 380 Auto they found out they couldn't get it. I ran a group buy for my
TLC358-100-RF but should have my inventory of this mold available soon. My
TLC358-125-RF will come in a little later in the year but Bull Shop is casting this larger bullet.
