Teslong bore inspection for carbon rings.

[SuperCub]

PS - This is what ca 120-ish rounds of SK-RM 'leaves' in the leade. And 1-hour of C4, then a nylon brush will get it gone. This is in a CZ-457 VMTR. Before and After

Proper cleaning of a 22LR is next on my list. All I ever owned in the past was a 10/22 blaster that never got the bore cleaned. I recently bought a older Walther with HB that should see more attention. I'm not going super serious with it but would like to see it shoot as best as it could and see what happens after that.
