Just got a Win. M70 Classic in .264WM and will be working up a load soon. Whitetail at 20-400yds. Always used 140gr. Sierras in my 6.5x55 with good results but got the .264 for speed, obviously. I always want a through and through pass through with my bullet. I am assuming with the Barnes TTSX excellent penetration and weight retention that I will not have any problems with penetration? Thinking I can get these North of 3500FPS?
