I asked BACO to make a modification to their 44 caliber bullets and they were kind enough to do it. Got the mould last week and cast up a batch. Today I got the first chance to shoot them in my 44-77. Had two loads one with Olde Eynsford 2f and the other with 1.5. Both loads held an honest 2moa when the wind didn't blow me clear off target at 800 yds.
Temp was 91* and the humidity was at 15%. The fouling from the Olde E stayed very manageable.
The2f loads (74 grs) only took 1 damp and one dry patch between shots, the 1.5 took 2 damps and a dry. I think a bit more compression on the 1.5 loads and they'll shoot just as clean as the 2 did.
Very happy with this new BACO bullet , cast from 20-1 it comes in at .434 diameter and 480 grs. Wrapped them in Seth Cole 8lb patches cut 1 inch wide. The wad stack was 1 muzzleloader original dry lubed felt wad, and 1 rubberized cork wad punched from my Cornell wad punch. Cases were Jamison primed with br-2's.
