So I've been playing around with loads for my 45-120 highwall decided to try some black powder.made a drop tube.dropped cigarette rolling paper wad over the flash hole dropped 120grs of 3f squeezed a 535gr round nose over the top. Fired about 5 of them figured it was kicking pretty good.allways thought the gun was a little light so weighed it just under 9lbs. So the question is how does that stack up to a nitro express round.or a 500 Jeffery
