Peter:

I assume you mean ".25-35" for the "25-30"? No, I was just curious where the pressure of the black powder .25-36 Marlin ranked when compared to the semi-smokeless .25-36 Marlin.

2-piper:

The 1894s may have been designed from 38k psi max. I've found a 42k psi value for 26.7 grains of HiVel3 behind a 60 grain HP in a Niedner S.S. rifle for the 0.25-35 & 32k psi for a 16.5 grains of Lighting behind a 117 grain bullet for the .26-36 Marlin with a corrosive primer.

Kind Regards,
