Rifle is a .45-70 Pedersoli Down Under Sharps, 34" barrel, throat is .460", grooves are .459"
One or two cavity, aluminum or cast iron. Must drop 1:20 at .460" to .462", no HP or HB styles. I prefer lots of lube groove for long barrels, my usual lube for boolits I cast is LBT blue soft. Purpose is strictly ringing steel at 100-300 yards. Loads will be smokeless. Please provide specific mold numbers as some makers have dozens of designs.
325-375 grain weight range
400-450 grain weight range
PS- with .459" commercial boolits, hard (Lasercast) or soft (9 BHN from a friend) this rifle leads badly. Badly is defined as fire 20 rounds then push 25-30 grains of lead out of the barrel. Yes, I actually weighed what I pushed out it was so bad.
