6PPC Bullets

[BP1]

Having a 6ppc built and a buddy of mine gifted me 2500 of the 65gr MO-JO Gentner BT bullets ..I’ll be shooting them out of a 13.5 twist..to all that have shot them before did you find them to shoot Jumped or Jammed? Thanks!

I'd start at hard jam and work my way out of the lands. You'll find a sweet spot between .010 in and .010 out. You'll read a lot about jumping on here but I can tell ya that the majority of sr br shooters are either jammed a bit or jumping very little. Starting at full jamb, leaves only one way to go, fwiw.

I agree pretty much. But I have had several barrel that I never took off a square mark that were winners.Never jumped but one barrel in ppcs or 6brxs.

I’ve actually kept track of this for a long time. I’ve found that a square mark, 10 in and 4 off are recurring successful depths.
