RE: .44-77 PP bullets.
Kurt,
I'd have to look that up, my rememberer doesn't work too good sometimes. It's a groove diameter ppb but I don't recall what the bore diameter is.
Well that's not quite true either, I patch to the freebore diameter, which is .510". The groove diameter is somewhat less than that. The rifle has a .510" dia. x .350" long freebore. The stubby little 490 grain bullet works very well in that chamber.
