I am getting ready to try loading some rounds for more precision than I normally do. I am starting out with new Winchester brass that has been Fl sized with a Redding die, neck sized, trimmed to length and chamfered. I also uniformed the primer pockets as well as ensuring the flash holes were deburred and uniformed.

I will be checking the bullets for consistency as well and using any that fall out of the "norm" for foulers.

What I was wondering what seems to be the most consistent primer of what I have on hand.

I have:
CCI 400
CCI 41
Remington 7 1/2
Wolf Small Magnum

I am leaning towards the CCI 400's because I have shot some really great groups with them before, just not with this barrel. I am not shooting competition or anything like that but I just want the rifle to be as accurate as I can.

The rifle itself has been headspaced to only use these handloads and I have shot a few rounds without issue. Those had CCI 400's with 69 SMK's over Varget. It has a newer 26" long 7 twist 223 barrel that I recently installed.

Thanks
