My pet load for my Browing A-Bolt is 140 grain Nosler BTs, 47.0 grains of H4350, Remington brass and a Federal 210 primer. Velocity is 2743 average (over 50 samples) and the Standard Dev is 15 fps, so it is pretty consistent. The good thing about this load is that the BTs and the ABs group to the same point of impact and my A-bolt prints both into less than an inch (5-shot groups). My average is 0.731" with the BTs and 0.971" with the ABs (both average of ten 5-shot groups). So, I can load up and practice with the cheaper BTs and use the ABs for hunting.
