Now, I guess I should size and trim some 5.56mm brass. These will be my first .223 reloads. Do all these numbers seem inline? Trim to 1.750" Seat to 2.200" (or perhaps a bit longer...we'll have to see where the cannelure falls) 25gr H335 CCI #41 primer (I also have CCI 450) Wanna kill these ads? We can help!
