Has anyone loaded the 80 gr Tac-XP into the .357 sig? I know Double Tap has them available and I am going to try to replicate their load as close as I can. They are showing 1755 fps out of a 4.5in barrel. Right now I dont have a chrony so I was looking for data that someone has used ( start, max and OAL would be great). Wanna kill these ads? We can help!
