Home Forums Reloading Big Game Rifles 7x57 and 140gr TSX and TTSX

I shoot the 140 TSX with H414 in my 77 MkII and have for years. Switched to the TTSX recently, couldn't tell any difference. My rifle isn't a picky one since it shoots .6-.7 with 140 TSX, 140 Sierra, 139 Hornady, and 160 partitions.
