While back I acquired an original 74 Sharps in 44-90 DOM 1874. Bore is excellent. Two problems had to be solved to test the oldster for accuracy: 1) put on some decent sights 2) get the correct bullet
1) After much run around by the top tang sight makers I found one who would alter a base to fit on the gun without drilling/tapping sight base holes in the tang. No way, no how would I drill an extra hole or two in this gun!
2) I Used the MM design program and designed a bullet I thought would give the best chance at top accuracy in this gun. The groove diameter in "Billy Dixon" my nickname for this rifle, is .448. The throat is old style tapered. I selected single cavity, iron mold. Selected cast diameter at .449 with a tapered front drive band. Weight selected at +/- 425 gr. Nose length at .510. Meplat is minimum at 41% since all the originals had long roundnose profiles. Selected 4 groove/band option with GC shank.
Got the mold as spec'd. As usual.... perfect! Thanks again Dan.
Cast some up using an alloy of 10 BHN, my standard for lower pressure, lower velocity for most old original guns. Sized with push thru to crimp the check and pan lubed with modified Felix lube.
Used some 44-90 JASS brass I found locally and tried a mild load of 5744 plus 1gr Dacron fluff filler and seated bullet to just touch lands. No crimp.
Went to range on calm day, set up chrono to get baseline velocity, and shot 2 foulers at the gong. Shot 5 thru chrono on a bull set at 50 yds. Below is a pic of the gun, cartridge, bullet and target. I think it speaks for itself.
