.45 Caliber Browning Mountain Rifle.

When I had my .45 Pedersoli Kentucky cap, it loved 40gr 3f Goex for accuracy. Never shot it for hunting though so I have no high vel loads.

45-70 should be the range for most accurate.

It depends a lot on the rifling. If it is rifled for balls 70 Grains is way to much powder for optimum accuracy?

I have 4 .45 rifles; two are flintlock and two are percussion. The two percussions like 60 grains of 3F while the two flint .45s do well with 60 grains but better with 70. I've used 40 grns before and the results were far from shabby. My .50, for instance, shines with 30 grains of 2F at 30 yards.

I got the same results years ago I found a load that worked and could go down with the charge with good accuracy but if I went up not very good results? I could shoot 100 grains and hit a 12" inch circle at a 100 yards but the group was all over the circle. That is not good.
I think I posted this once already?

I have a .45 JBM rifle also. .440ball, .15 patch and 50 grains(PV) 3 F black powder. very accurate.

I agree, most people think they need much more powder. Early hunters cupped their hand and covered the ball. LUNG SHOTS!

I agree with that. You don't need as much powder and velocity as you think. I read an article in the Backwoodsman Magazine about guys using large bore .50 caliber air rifles killing some really large game with .50 caliber round balls. And their start velocity was only 800fps. Hitting where you aim is more important than super high velocity. Plus your patch will survive better with a lower powder charge.

You guys use an awful lot of powder in a .45 rifle....
