Not worried about accuracy so much as I was concerned with them coming apart in flight.
Shot many thousands of 40gr Blitzkings through an AR and had no blow-ups. my AR's were 1-8" and 1-12" twist barrels........5 and 6 groove barrel's
Only time I have seen 40gr Blitzking's blow-up in flight is with 22-250 and 220 Swift with 1-8" twist 3 groove barrels, with 223 speeds you are safe with 1-7" twist even with a 3 groove barrel.
Having owned a few AR barrels and shot many 40gr BK's a 1-12" barrel is more accurate with this bullet........WOA !!!!
