I have a 264 Win Mag. Love the rifle, great caliber. Only real regret is the rifle has a boss on it. Trying to figure out the proper sweet spot setting on the rifle for what I am shooting. The only thing they list is the 140gr. bullet because it's the only size load ever manufactured for it. Right now I am shooting a 120gr. Barnes TSX.
If anyone could give me a close setting to start with to find the sweet spot I am sure it would save me a lot of time and a lot of bullets...
