I must move within social circles with those who are cognizant of effective ballistics, because hunters regularly tell me that their main big-game rifles are chambered in .270 Winchester.
Always searching for a step up in performance, I couldn’t help but notice that the Alliant Powder Reloader’s Guide (alliantpowder.com) lists some impressive velocities for the .270 Win. firing 150-gr. bullets handloaded using Reloder 26—Nosler Partitions, Sierra GameKings and Speer BTSP 150-gr. bullets managing slightly more than 3000 f.p.s.
