Ok, here is my latest group. I'm starting to think I may be the problem here and not the gun. I am shooting hornady SST 150 grain. I think I might try the 165's or 180's, but from looking at 3,4, and 5, I'd say it is capable of shooting sub moa. I am shooting from a Caldwell lead sled as a rest. There were no adjustments made during this group other than me changing the parallax setting on the scope and perhaps just doing better control on the later shots. I was better about waiting a long time between each of the shots to allow the barrel to cool, and I paid attention to the grass on the side of the range as a wind flag. Right now, I think I'll hold off on the cut and crown and focus on load and practice.

Thanks for the reply.
The accuracy has been an issue for me, but I am unsure if it's just the ammo or something else, like this damage perhaps. I just remounted the action/barrel assembly to the stock making sure the piece in the stock bedded properly into the slot in the receiver. I loosely installed the action screws and bumped the butt of the gun to the floor and torqued the action screws to 50 in-lbs by starting with the forward action screw and stepping up in 10 in-lb increments alternating between the two screws. I remounted the scope and base as well. I have a DNZ mount on it and torqued the base to 30 in-lbs and Nikon monarch scope and torqued ring halves to 30 in-lbs, again alternating from side to side in increments. I then started cleaning and noticed it had a lot of powder fouling in it and noticed copper fouling in the end of the muzzle. I went and got a bore guide and a 1 piece carbon fiber cleaning rod to start cleaning it the right way. Upon cleaning the copper out with a copper solvent I noticed this damage. The copper had effectively filled in the damaged areas. I have only been to the range once since and forgot my rest but shot it 5 times to foul the barrel. I plan to take it to the range and try a group and see how it does now. Before all this I had gotten the gun to group sub moa once before, but since had been around 2 moa and all over the place. Could just be me shooting on windy days, but I try to wait for pauses in the wind and I don't have access to a 100 yard indoor range.
I guess I need to go shoot it now and see what it does. Like you said, if it shoots good I probably won't worry about it. If not, I may try some other ammo options or bullet weights. I'm shooting hornady SST's now. I tried just about everything Remington, Winchester, and Federal to no avail. Any other recommendations on ammo to try that others are having good luck with in their tikkas? If all else fails, I guess all that is left is to cut it and crown it.

Bump. Anybody else seen anything like this? Any other ideas what could be the cause? Still finding it hard to believe cleaning could cause this damage.

Being a bolt action rifle, I always removed the bolt and cleaned from breech to muzzle. However I would pull the brush back through from muzzle to breech. I also wasn't using any type of bore guide and was not being especially careful.
Any recommendations as far as a good gunsmith for this repair?

I did a barrel break in procedure in the beginning which is why that number is rather high. Cleaned it after every shot for the first five shots and then every 3-5 shots for a few times. I recently purchased a bore guide and a carbon fiber rod and am being more careful with my cleaning unfortunately the damage has already been done. I have been having some accuracy issues which is what led me to finding this in a way. What are my options to get this fixed? A simple recrown perhaps? Thanks for the replies!
