I'm using a major maker's HiTek coated 125g RN in my Glock 48 9mm. 4.5g of CFE Pistol over a standard Fed pistol primer, OAL is 1.11". And I'm getting horrible leading, after no more than a few magazines. The leading is on the face of the muzzle and the interior of the barrel viewed from the muzzle. Bullets measure right at .356 before loading. I pulled three loaded rounds. The coating is perfectly intact and the bullets measure consistently at .355 after crimping with a Lee FCD. I know Glocks have a bad rap with standard lubed cast, but I thought the HiTek coating was ok? Is this just a Glock thing or do I have something else going on?
