Barrel liners for breech loading rifles & pistols are hammer forged of special Chromium Molybdenum alloy steel, in the U.S.A. Each liner is hammer forged over a special mandrel, producing an extremely smooth and uniform bore of the desired dimensions. We offer these calibers, twist rates, bores, and diameters.

I was given the go ahead to try and salvage this barrel with polish, if it fails I can still swap it for a new one.
Well I did get a response, and the option seems to be polish it out or ignore it. I did mention that the barrel on my cheaper Kral did not have defects inside and at the premium prices this is going to be an issue. I was told customer service will ask if it holds accuracy, otherwise nothing will be done. So that's another $50 to $100 in the Benjamin Nosler rounds to prove out if it is accurate for something that I know has a problem.If the first one didn't bite me, I'd have never bought that scope and never been critical of the process. Maybe my expectations are too high. Maybe I should have bought a different brand. There are options, but I'll say that this may be the last straw for Crosman and me.I have started to look at other barrels, the big issue is lack of a lathe. Almost all of them come in 1, 1.25, or 1.5 inch diameter, that's a lot of cutting and possible bending. And at 28 inch long a big machine (through spindle you are lucky to get 1 inch in the smaller machines, 20mm is more normal). Barrel outer diameter is around half an inch (never measured). I'd like to make this a 45 (.452) and with a 35 inch long blank was around $150, I'd guess another $200 - $300 to machine it down and maybe ream the chamber. Then I'd have to make a probe too. Going down to .257 would be possible, the barrel won't get as thin in the receiver area and Mackeral5 has already done this so I could follow along and maybe get help. AEA is kicking backside in power and accuracy seems good, and at half to 1/3 the price. Those new "premium" $1000 guns better be perfect, even though this Bulldog is up in the premium territory. I want to like it, I want to support the closest local company I can, but this is making it hard. The barrel lottery still exists and it's not a good thing since all I'm doing is wasting money on tickets. Should I tear into one other issue I've seen between both these barrels? Yes it is a manufacturing issue that is totally preventable.

If you interpreted it that way then that's on me for not clarifying it. The first option I gave you was to send it back in and wait for a new one to be return. This was taking ownership of the defect and wanting to make it right. The second option i gave you was more about convenience. You had already spent a bunch of time cleaning the barrel and mentioned about wanting to polish it but didn't want to mess it up. So i said you polish the one defect that you were worried about. That way you have it there and don't have to ship it back or wait for a new one. Plus since I said you could do the polish and you were worried about making it worse I would make sure it would be replace if the problem didn't go away. Yes you would have to shoot the rifle with your ammo of choice. Phillip
Phillip,What would be the best way to polish the defect area Greg pointed out? I have strong opinions, but that does not make me right.Thanks
I should have phrased it better that I can ignore it and hope it goes away.Honestly, I can't see how polishing this will take down a burr, but not wallow out the barrel. Its all the same material. Without building some kind of selective cutting tool, I can't see how it would wear just the high spot down. What I think I might try is pushing a round from muzzle to breach and seeing if it will catch and break off. The pure lead doesn't show much damage, too soft and too shiny, maybe I'll have to sacrifice a Griffin round since those have had time to darken a little.The only reason I already polished it was to remove surface rust and try to clean up some of the other marks. Yes there was rust in there. Maybe I should have rejected it after cleaning. Or maybe my expectations are too high, but this isn't a $300 cheap import either.And I will say that if I reject it, it's junk and should be destroyed. Or at best cut down into a short carbine.Based on the barrel links above, I measured 0.685 outside diameter where it mounts in the receiver, a 5/8 barrel should fit nicely with a small sleave. This thing may turn into a 45 yet.
Honestly, I can't see how polishing this will take down a burr, but not wallow out the barrel.
