Ive just put together my new 223 AI and have my brass fire formed and old components used up now im starting to do my load development does or has anyone tried the 450 Mag Primers and did it make any difference for you? Im loading Varget with the 75gr Amax?


thanks Hillbilly
 
Try them and find out. The 7-1/2BR and BR4 have always worked well for me. Do your load sequence with two different primers and compare them. Sometimes there'll be no difference, sometimes the difference will be surprising.
