The slot is too shallow to remove, but it irks me to be charged $54 for a cleaning, then they will check to see if they can fix it. Anyway, off to my smithy to repair. I have anti seize and will dope a little on the threads before I shoot it again. Been wanting a .32 for a while. My Beck is rough and hard to push a ball down it after 2 shots. Bore is rough, but still shootable. I use black powder, not the modern stuff. I think later I'm gong to remove the glossy blue, and brown rust it. This was mail order, and I hoped for a more realistic rifle like my old timer.
