I am currently loading for a Pedersoli model 1886/71, .45/70. & my Sharps with GM bl. chambered in .45 1.9". I load the Sharps with 48.0gr. Benchmark and 405gr.
RP bullets, for 1,850fps and 10 shots into 7/8" @ 100 meters off bags with aperture sights. It allows slightly longer loading than a Marlin 1895 so data is about the same, but higher speed dur to the 35" bl.
So far, in the '86/71 I am just using Bullet Barn 450gr. BB FN's with Hodgdon's Benchmark powder and fairly light loads, 43.0gr.(1,500fps) to 47.0gr. at a guessed at 1,700fps.
Very accurate, but not loading very hot.
According to Hodgdon's Annual Manual, I should be able to go up to about 55 or 56gr., but have no real desire to do this.
I can ring the 200 meter 14"x 16" steel plate time after time offhand with this load - good enough.
I have a bunch of moulds in the 350 to 560gr. weights, so should start loading. I am interested in the powder coating as shown by Trailboss.
I ordered and received some powder, but ordered the wrong stuff and ended up with 2 bags of Cerakote. LOL
