Even Barnes will tell you that they like a pretty good amount of "jump" into the lands.
I have had bad results seating them just .002" or so off like most of my other bullets like. If you can,try them about .008 - .012" off. As a byproduct you can boost up your load slightly.
These bullets should have max (or close to it) velocity,and you should always hit bone going in. I put any TSX or TTSX square on the shoulder if possible.
Even the Barnes TAC-TX kills great at 2380 coming out of my 300BLK's. Super accurate also. --- SAWMAN
