[QUOTE="MoBoost, post: 2141582, member: 3455"] Savage has 120 rounds down the pipe. 223 AR-15 has 40 round count 556 AR-15 has 7000 rounds of Tula and whatever else through it Both RPs shot through AR-15 have flattened and slightly raised primer. I was seeing if 556 NATO chamber has pressure reducing characteristics over 223 - that's why I went with the combo that I knew was on the pressure limit, small change would blow the primer out. I don't see any difference between the two. 92gn Win has enlarged primer pocket now 94gn Win is destroyed, the rim is flattened and won't fit in the shell holder. [URL="http://www.midwayusa.com/product/3083212767/tulammo-small-rifle-223-remington-primers"]Tula 223 primers[/URL] are very hard, and I had ignition problems before adjusting the firing pin; I am going to back it off since I'm switching BR primers anyway.
