22LR chamber Reamer on an Erma Werke LA-22

Erma Werke LA-22 chambers are not a sporting spec chamber. Many 22LR bullets will hit the rifling before the bullet seats all the way to the rim. In the video I use a chamber reamer to fix the problem. It would shoot nearly every ammo brand I tested it with and did not have the same issues I had before which was the bolt would not slam shut all the way more than half the time unless I used High Velocity ammo. Ammo I tested with prior to chamber reaming was same ammo I tested after. Only Thunderbolts would work before doing the reaming. Afterwards, it worked with: Federal Automatch bulk Winchester 555/333 Remington Thunderbolts Remington Golden Bullets CCI Standard CCI Minimag 36g HP CCI Minmag 40g
