Pitting in barrel

Postby Big10Inch » April 4th, 2011, 4:18 am

I did Clark's deep clean this weekend on two guns.

1) My Browning Auto 5 is about 15 years old and I have put 30-50 boxes through it and the bore looks great after the deep clean.

2) My girlfriend's Model 870™ Express® Shurshot™ Synthetic Turkey is two years old with only 30 shots through it. After cleaning it twice, there were two noticeable pits about four to five inches from the muzzle and 'machining' rings all along the bore.

Will this have a big negative effect on the pattern? Should I bring this to a gunsmith to fix it? If so, what will a gunsmith do to fix the inconsistencies?

Both guns have been cleaned, oiled and well maintained.

I tried to get out shooting yesterday, but there is still two feet of snow in the gravel pit and on the bush road where I go patterning. As a result, I cannot provide any patterning results yet. Our season opens on April 25, so I have a little time yet.

I watched a video from midwayusa that Larry used a rod with honing stones in the barrel to clean it up. Maybe that is how they get pitting out.

Hey Peter,

There should not be pits in that barrel, nor should there be noticeable machining rings. Are you able to feel those pits and rings, maybe with a pick of some kind, or just see them?

Have you tried some additional Hoppe's with a brush in that area, from the muzzle, just to make sure it's not some surface "gunk"?

I've seen some really bad looking barrels throw great patterns, so it may not effect performance but it does effect value.

Since it's such a new gun, Remington would probably replace it.

Today, I spoke to the retailer that sold me the gun and he will send it off to Remington for their opinion... after the turkey season.
