[QUOTE="Hugnot, post: 2309474, member: 115658"] Here are some primer & target photos. [ATTACH type="full" alt="IMG_1549.JPG"]303836[/ATTACH] [ATTACH type="full" alt="IMG_1551.JPG"]303837[/ATTACH] The first image is a shot of a CCI 450 (left) and a CCI 41 right. The CCI450 is nickel plate and the CCI 41 brass. There appears to be tiny bit less anvil protrusion on the CCI 41 (brass) than the CCI 450. I have not actually measured the anvil protrusion but plan to do so with a small bunch of primers. I would be surprised to see any variations more than .002 with most less than .001. The CCI 41 is my goto small rifle primer and I use them in : .20 Practical, .204R, .223, & 6.5X47 Lapua & have plans to use them with a 6mm CM & 6.5 CM that are in the process of being built. The target shown is a 300 yard group shot with my 11 twist .20P rodent rifle with 40 VMax's, LC 5.56 brass & IMR 8208. I have no plans to discontinue using 41's and hearing other shooters reject them does not cause concern - been using them for years. Big piles of dead rodents of all species - up to 400 plus yards.

I have never fired the NRA HI Power course with a .223/5.56 but understand that fast twist AR .223's are used with 77 grain bullets at 600 having rounds that are too long to fit inside a magazine. Is there some type of a "sled"(old past Garand shooter) that will allow single loaded 77 grain bullet round to be safely chambered? edit: found a sled (Bobsled!) for my AR so I won't waste lots of bullets & can shoot 75 ELDM's way out there.
