you should realy try a .015 patch. That .150" patch really cuts the ball size down and is difficult to get to shoot well. I'd expect a .220" ball might be the largest usable.
: Just kidding - misplaced decimal point is all.
: 80gr. 3F should give in the 1,800fps to 2,000fps range.
: Ft lb. energy is meaningless as a guage of killing power. Suffice to say, if this load shoots accurately in your rifle, it will do for deer to 125yds. just as it did in the 1800's. On Moose, I'd hold the range to 80yds. or less for broadside penetration to the off side thorugh ribs only. Stay away from shoulder bones on either game animal.
