A Barnes TSX, TTSX, and MRXare going to operate at a lower pressure and have a higher velocity due to the reduced bearing surface of the bands...so it will tolerate a higher powder charge.

A nosler, having much more bearing surface, will generate a higher pressure due to it's typical construction.

Never assume that powder weights will cross match with other bullets without first doing a work up.

When in doubt, always play the Safety Card....
