Question about 9mm magazine block

[XXFattyHunterXX]

Thanks for answers. I have the plastic orange follower, my bolt locks back all the time when its empty. The mag wobble made sense what Great-Kazoo said. Aluminum and brass ball ammo goes through fine, not the case with hollow points, even have the Wolff XP spring too seeing if it helps but no luck.
My build consists of:
Complete CMMG lower
CMMG Ramped Bolt
Adco 7 inch barrel, BCM upper
