Yep about 400 .223 all with SP primers.
Been reloading for 14 years. First time using Cci , recently purchased to shore up my primer stock.
Lesson learned
depends on what your loads are and the pressures it will generate...
Under Obama's Debacle, I mean Administration, frequent all we could get around here were small pistol primers..
I shot a lot of them during those 7 plus years under Obummer... just kept my pressures low and they worked out fine.
Even under O'Biden, I was running loads all winter with the 223, 9 grains of Unique and 50, 52, 53 and 55 grain bullets, ringing steel at 300 and 400 yds with them...wear a pair of safety glasses just in case, but in a couple thousand rounds, didn't notice any problems, pierced primers etc. YMMV...
