[QUOTE="Dirt_Nap, post: 2951108, member: 51704"] I'm reloading a bunch of Hornady 55gr FMJBT in LC brass. I've been using Tac powder with 32.8gr powder. Unless I'm seeing it wrong, my Hornady load book puts 23.8gr at about 3000fps which is where I want to be. Trying to shoot for M193 velocity give or take. Chrono shows my loads at 2770fps +\-. What am I missing and why are my numbers so different than the book. I understand the Hornady testing is a 20" barrel and I was using a 16" barrel but still seems off. The IMI M193 I also tested in the 16" came in pretty consistently at 3050fps [/QUOTE]
