I had a CZ that only liked brass - even when newly clean I wouild maybe get one flawless mag and then feed problems one or two a mag. The happened with Wolf and CCI aluminum. My XDM works well with all brass and the CCI but after about 50 rounds with the Wolf it starts having trouble. Like many have said depends on the gun. I shoot 115 on the range and 147 for USPSA all factory - have not gotten to the reload yet, still on the bucket list.
