77 grs of OE 1 1/2 with a .030 fiber wad and 1/8 in felt wad under a 1.1 inch patched bullet will go over the chrono at the claimed original velocity. Makes one think the modern 1 1/2 designation probably a lot closer to the 1f of back in the day. 83 of OE 1f fills the case to just enough room to seat the wad and then compress enough to seat the bullet.
The original bullet sent to me from a pull down 44-77 creedmoor load is a tapered bullet with .438 diameter, 1.3 inches in length and weighs 460 grains. You can see on the bullet that it was seated about 1/2 inch deep into the case.
Putting a new unfired loaded round into the Shiloh chamber and then firing, what comes out makes you think you're fire forming modern ackley improved.. LOL
