125 Yards Texan 50 460 grain N.O.E Mold powder coat

[RM.510bigbore]

Perfectly clean bore. 2 shots to fowl barrel. Next 5 accurate as you can see. Next 3 shot group Was over 3 inches. In my experience these are the results that drive you crazy with rough bores. If I clean after every 5 shot group all is well. When I have the funds I will buy a custom benchmark barrel!! The barrel is straight just rough!!

Tons of good info here on barrel polishing! Might give it a go. Looks good otherwise!

There is no way in the world I would do anything to replace that barrel until I had tried to smooth it out. It shoots way too well. Anytime I receive a new air gun. I clean it with JB bore paste. I scrub it each time. I do this until the bore no longer fowls. 

Should be relatively easy to do on a large caliber like that. You don’t have to worry about rubbing the walls of the barrel with the rod.

I’d be so happy with that! What a heavy hitter, I hope you can get it smooth. Great shooting.

The holes don't look round like seemingly they aren't stabilizing correctly?? That is unless the target was biased down and to the left quite a bit??

My target backer isn't perfect. That's all. I need to straighten out the mining belt when it gets warm and is flexible.
