Anyone know what these were designed to be loaded for?I have an old 1980ish box of Winchester 30 cal. 180 grain Silvertip component bullets. Looking to load them in a .308 for hogs.I know 180 grain is a bit heavy for .308 but unless they're designed for .300 WinMag velocities they may work fine for 100 yard or less hogs.If they're too tough to expand I'll save them for something else
