My CZ mag's are 2.325" tight,which is ASC AR mag confines and why I love them for 75 HPBT's in 223 and 88's in 22 PPC AFI. Hint.
While COAL is obviously a factor,the .100"++ leap to the lands,do no fhuqking favors. Hint.
The Mini is best in 22 PPC AFI,followed by 243 Grendel and lastly 264 Grendel. The shorter case,with greater capacity,simply slams doors shut and rules the roost. Wayne's World BDL metal,do many favors,while OEM and CZ DBM's do not. Hint.
Identical COAL here. Hint.
Just sayin'..............
