I have two Canik pistols in 9mm. They are a Mete SFT and the Rival. The problem is that after 2 or 3 shots there is a build-up of lead or PC coating at the front of the chamber. After 2-3 rounds the next round will not go into full battery.
I am using a .3560 sized bullet in both lead and powder coated. Both ways the build up occurs.
Slugging the barrel reveals a .3545 bore diameter. Bulet profiles are round nose and TC.
I also taper crimp to .380.
Any suggestions?
