    Theoretical range card calculations.....

Service". The US "Ordnance Manual of 1861" gives a standard .577 cartridge containing 60gr though (albeit a...

I've been trying to locate reports from the ordnance department of testing...

    This might be a slightly strange one... I used to be a target shooter many, many years ago and enjoyed the process of zeroing and building range cards immensely. I havent shot for a long time but have recently been playing a PC game based around the US Civil War. I have become somewhat...
