30 gr? The barrel split scares the heck outa me but I use 24 gr H4198 behind a 520 gr pointy tipped cast 20:1 bullet. Now for some more blasphemy...I also use just enough dacron batting to hold the powder agasint the primer. I've never found any after shooting. I'm fairly certain it burns up in the barrel. I regularly use a neck expander and seat the bullets approx 1/2 way in with my fingers. The bullet size, length and lube hold it firmly enough and when I stick it in the chamber the bullet seats itself in the case. Avg crony is 1129 FPS and it shoots .5 MOA at 100 yds.
It maintains the MOA out to 200 yds and I had planned on shooting it 300 yds this Sunday on Silhouettes.

My rifle is a 1997 Browning High Wall BPCR .45-70 with an MVA Malcom 6X, 28 inch scope.[Linked Image]

My thinking is this is a modern rifle using low pressures. Is this also an accident waiting to happen?

Thanks

I also shoot an original Sharps 1859 .45-100 but I use BP in that one.
