My 70FWT shoots 120 and 129 grain bullets very well with either 7828 or R19. Playing with 140s has always seemed a bit hit-or-miss perhaps partly due to trying to get SSTs to shoot well. My better loads with them have been mild loads of I4350 (which kind of defeats the purpose of their sleek profile). Recently I found some 140 Interlocks and decided to try them with H414. THat seems to be a good pairing and hopefully it will also work with other 140s - although I the Interlock is perfectly fine for most of what I use the 6point5 Swede for anyway. Admittedly the M70 spins bullets a bit faster than your rifle, but perhaps it offers a clue .
