I got the above mold in a trade, been working with it, a little Leementing, a little lapping and the boolits are literally jumpin out of the cavities at .360" . Been putting them through my GP-100 with some WInchester 540 in 357 cases. Started at 7.5 grains and that would be a fine plinkin load but have been up to 8.5 grains and it is startin to show some promise, seem to be more accurate than at 7.5 grains and I was just shooting off hand just getting a feel for the load, I will get it up to 9.5 grains this week. At 7.5 grains after 25 rounds I had some leading, it came out when I ran a tite patch down the barrel, at 8.5 grains after 50 rounds there was no leading at all on the patch. I do find that the Win 540 seems to be kind of dirty. So far I am quite please with this one. I will be making a new size die for .358" and try them in my Browning High Power.
