Does anyone have a favorite load for the T/C .58 Big Boar? Was thinking roundball, but open to conicals as well.

I know that the Big Boar is a 1-48 twist but according to the people I talk to that own them, they shoot roundball real well. .58 caliber conical bullets are hard to find and expensive. Also nothing walks off from a .58 roundball. One person I know that owns that rifle shoots 110 grains of 2f and a .570 ball and patch.

I have a .58 caliber also but mine has a 1-70 twist. Mine shoots 110 grains of 2f and a patched ball as well. Start your testing out at 80 grains and work it up from there. That is a great rifle. I still kick myself when I had a chance to get one and passed on it.

.58 load

I have a Navy Arms .58 Hawken hunter @6 " barrel ,1 in 60" twist . It will burn Up to 175 gr of ffg ,with a wad under a patched RB. It stays on a 8.5x11 paper off hand at 50 yards .This load came from the late Val Forgett, and may exceed your comfort level

A moose hunter I guided had one of them. He'd put a ball in his hand, and pour on enough black powder (goex ffg) to cover the ball. That did the trick, as Cayagud confirms, a 56 inch bull did not "walk off". He tried to, but went down after a very brief stagger. The bigger diameter ball you have should work just fine in 1 in 48. If I didn't need a scope, that caliber (at least) and round ball would be my choice. Just plain fun to shoot those RBs. Beats heck out of the cons.

I'd start with 60 grains of 3f and work my way up. When accuracy falls off back up a little. I doubt more than 80 grains is needed.

My answers are mostly of no use, being as how we are in different worlds!

I shoot a .58 Pedersoli African Express Double

I have used two conicals which will not be available to you!
both worked very well!

One was a 515 grain conical made by Bushveld ML Supplies - best description would be a slightly modified Plain bullet

Another was a modified Minie, also by Bushveld ML Supplies - here the Traditional Minie is modified so that the hollow base is reduced to a shallow sauce pan shaped hollow - weight is 590 grains

Have also have good success with .58 cal REAL cast from a LEE Mould - weight is 440 grains

I have used 100 grains Sannadex Pistol Grain BP substitute - equivalent to about 90 grains FFG
