The American Sharps Shooters, 2015-3

[Tom Herman]

Tom, That old original might do well with the Spencer bullet. The old Springfields often had a 1 in 42 inch rate of twist which really wasn't quite fast enough for the 450 grain bullets. Shoot sharp, Mike

Mike, I am leaning towards the Spencer bullet: I believe it has a larger diameter than the standard 435 grain bullet mould, and I'm aware of the slow twist rate not stabilizing the Government bullet at distance.
So, the Spencer should be a winner on all fronts: Lighter, thus less pressure, better stabilization, and easier on the nearly 150 year old gun!
Thanks for posting pictures of your 50 yard target: That is some fine shooting, and an even finer gun!
