Have you guys ever tried 0.356" in the Slayer?.... A lot of PCPs shoot best with bullets 0.001" under the groove diameter, with no loss of velocity (most of mine even gain a few fps at 0.001" under)…. and boy, do they load a lot easier....Bob
Just a hunch Keith but I bet if those Hornadys were 358 they would shoot a ragged hole at 50. The only 357 sized bullets that shoot in my Slayer are the 142 NSAs. Everything else has to be 358
