I bought 100 158 gr XTPs to try with Lil Gun for my 4" ss GP-100 357. I would like to use 125 gr bullets, but can't find any load data for them. I have a 357 reloaders guide and Lee's Modern Reloding 2nd. Lee doesn't have load. Only Hodgdon listed load data with Lil Gun. I used 16.7 gr of Lil Gun and spm primers col 1.587" with the 158 gr XTPs. Pressure is supposed to be a lot less than with most powders. Wanted to use Titegroup, but its been sold out for over a month. Anybody else out there using Lil Gun for 357?
