After gathering all the reloading equipment and reading and lurking on different sites, it was time to get started. I have experience with C&B revolvers which led me to have a interest in loading my own cartridges. GP 100, 4 inch, .357. Bullseye powder, .38 -125 grain lead cast powder coated bullet. 20 ft off a rest. 2.7gn, 5 rounds, all through two holes 3gr all through 3 holes. Feeling good, I'm hooked! 3.5, cloverleaf, 5 distinct holes but still good.. 4 gn opening up even more, not liking the spread. Tried all of these in a SP 101 stub nose. The 101 did not like any of these loads. I an looking for a light, med and heavy load for the GP to load in bulk. Not sure how to proceed at this point. Here what I have, Bullseye, Uni and Trail Boss. 125gn RF, 148 WC, 160 gn RF, all are hand cast, Powder Coated and sized to .357. What would be the next step in this ladder to find the guns sweet spot. I don't know any other loaders so your input is highly valued! Also fired off some store bought ammo, not impressed, I thought it was the guns, its the ammo!
