i just switched from a very reputable regular fl sizer. to a full length type s bushing sizer die for bumping my 300 winmag. i know its mostly an already known fact but THESE DIES ARE AWESOME!!!it took my runout to .0005 without turning necks or anything fancy. these dies make good ammo easy. i ordered another set for my 308 gas gun. redding is head and shoulder above the rest.
