Never ever have pierced a person or cci 400 experienced a slam fireplace nevertheless but have only used about a thousand cci400s in my lifetime

Again, the testing seems to elevate additional concerns than give responses. The only definitive conclusion I'm able to attract from the info set up to now is this rifle appears to like the 40.8 grain load the ideal in Starline brass.
