This load has worked very well in every .50 caliber I've tried it in.
That's a LOT btw.
A Hornady 250 grain .45 caliber XTP in a Harvester crush rib sabot over 70 grains of 3f Swiss Holy Black. 1575 fps from my 24 inch Firehawk and 1610 fps from my 28 inch Hawken.
The Firehawk 1-38 twist.
Numerous inch/ sub inch 3 rounders at 100 yards. Smallest to date, center of hole to center of hole 5/16ths of an inch. Aperture sight, for full disclosure.
The Hawken, 1-48 twist.
Solid 1 1/4 to 2 inch groups all day. Also aperture sighted.
The 15th was our muzzleloader antlerless opener here in Pennsylvania, and I dropped my 15th deer with that load.
The only drawback, if it is one, is you MUST swab between shots. I use rubbing alcohol. Evaporates quickly, even when it's cold, and no damp charges.
Good fortune to ya!
