It's my understanding that the 6.5mm TSX comes in a 140 gr., but as yet I've been unable to find any. Anybody know if they actually make such a bullet, and if so where they might be available? Also, in another thread here on CGN, someone mentioned a 150 gr. TSX for the .303 British... wondering if that exists as well, and where I might be able to find some? Finally, I've loaded TSX's for 7mm Rem Mag, and have always stayed within the book numbers for the old X bullet. I believe it would be OK to move up to powder weights listed for the Barnes coated bullets of the same weights. Anyone with experience able to comment on this?
