Cz 527 grendel varmint reviews

[A5BLASTER]

Longest I have run in my 527 Grendel were with 130gr Berger AR Hybrid at 2.285 and they ran fine from it.

The 129gr LRAB I am running with CFE 223 and 2.27 IIRC and 30.6gr CFE 223 Standard not mag primers.

I don't think it's the length of the rounds that's the problem, seems like the mags have a bit to much play in the spring and when the rifle recoils it lets the rounds slid forward.
