Good Rebarrel Candidate?

[baldhunter]

After checking out this rifle with my Teslong bore scope I found the last two inches had deep annular tool marks through the lands and grooves.I did get it to shoot well after I fire lapped it,but I may just get it rebarreled,what do y'all think?

If it is shooting acceptably to you, leave it alone.
If not:
Last 2", as in near the muzzle? Cut off and recrown it.
Near the chamber, rebarrel.

I'm a results oriented guy. If you got it to finally shoot well after fire-lapping, then I'd just keep it and shoot it until it quits grouping for you. Still, it's amazing what you find when you look at a bore up close. Even more surprising when things look 'ugly' but still shoot okay.

It is the last two inches near the muzzle.It already has a 24" barrel so I really don't want it shorter.I think I'll send a note to CZ warranty to see what they say.I mean really a barrel with that many tool marks should never pass.This is on a CZ HA 550 HUNTER.If I keep my loads on the milder side I can get some groups down to 3/4" or so but if I try to push it They tend to open up.Longer bullets seem to do better too.

.75" groups from a factory barrel is not to bad. Tweak the charge weight and seating depth and see if they improve.
Also, action screw torque can make improvements too.

Do you want a new barrel? That's the real question.

Certainly something I might consider.This is what my PacNor barrel looks like.What a difference.

If you aren't happy with it as is, my recommendation would be to cut it and recrown as previously recommended, shoot it and see if the accuracy improvement offsets your dislike of the length, if not sell it and start over. Folks on here might not be interested, but your local market might jump on the opportunity to get a rifle that is verified to shoot sub MOA. I sold a 7mm mag with 37 rounds through it once for $50 under what he could have bought it brand new, because a friend told a friend told a friend...
Of course I dont know how much it would cost to have it cutoff and recrown, so that factors in.

What would cause tool marks across the lands and grooves at the muzzle end?

I'm always looking for a reason to buy another barrel

I would think it was done when the barrel was being bored.Dull tool or wobble,not really sure.Looks like two inches of speed bumps.

Usually those marks in the barrel are related to chatter of the cutter, which is driven by cutter wear, rigidity of the setup, barrel material/hardness and other little issues. The lapping should clean much of it, if the process was set up to remove enough material to finish it. Pure skill and experience in the manufacturer. Sometimes, bad ones get through....

Bad cleaning technique.

Nope. Those marks in the photo are from the OEM. Cleaning will not fix it. You just deal with it. Will it or will it not shoot? Look at the photo in post 7. That is a high quality barrel.
