if I'm correct the 50s are green mtn barrels you might ask them
50 caliber, 1:70 twist, 42" long, 1" across the flats, 1137 steel, single point cut rifled, air gauged, stress relieved, octagon black powder muzzle loader barrel blank >>>---> from their web sight

I should think it would be substantially more than any black powder load one would reasonably be expected to use.

I recall looking at some pressure stats quite a few years ago that showed the smaller the caliber the higher the pressure.
There are tables in the old Lyman Black Powder Manuals that have pressure values recorded. These books are from the 1970's, but basic formulation of black powder hasn't changed much since Roger Bacon wrote his formula down around 1260 AD. The formula was adjusted to its present ratios about 1520. While quality and purity of the components has improved the values in the Lyman Manuals are still valid. Now I will have to look them up.

I did that and discovered that my previous information/post was incorrect. Larger caliber = higher pressure. Don't recall where I got the previous information.
