Isn't that the patented Remington ratchet rifling I'm always hearing about ? Whatever they call it, I hope they keep it up.

I have no idea what they are referring to, THIS IS IT
Psalm 19:14-May these words of my mouth and this meditation of my heart be pleasing in your sight, Lord, my Rock and my Redeemer. _ Humble servant of Jesus Christ. Living His plan and praying to show it in name, word, body, and light.

Those look like waves from an out of adjustment hammer forging machine.

Take that X 3-4 and you have my original Ti. That photo looks slightly worse than the second one Remington sent me.

Never got this Remlin XS7 .308 barrel to shoot anything worth a damn with a wide variety of bullets, powders, seating depth, free float vs. speed bump, bedding, pillars, blah, blah, blah. Then I discovered this is what the bore looked like. Several trips to Remlin to make it right and to their credit, eventually, they just threw their hands up and offered to buy back the rifle.

I had a 40X barrel that had similar looking marks in the barrel. It shot 1/4 inch groups rather boringly though.

In general appearance, or depth too? Those look like they would catch a fingernail.

That looks rougher than mine did but I remember seeing those little grooves perpendicular to the rifling.

40x barrels are button rifled. If the bore reamer leaves circumferential marks they can still be visible after the rifling button passes, but they shouldn't be nail catchers like those in the picture.

It appears that Purdue either moved them, or is having trouble with their doc server. Anyway, the hammer forging machine that leaves such 'chatter marks' as the O.P. posted is poorly set up/adjusted. That doesn't automatically mean the barrel won't shoot, but it definitely means the operator or company wasn't paying very close attention to what they were doing that day. Would like to read the papers you linked but the links no worky for me.

Looks like threading for a "special" inside-the-bore muzzle device.

I always thought those kinds of marks were pretty typical of hammered or buttoned barrels that had not been lapped.
The 280 Remington is overbore.
The 7 Rem Mag is over bore.

Lapping the chatter marks out of my original Ti would have turned it into an 8mm-06.

I've seen several rifles with pretty rough bores from the factory. Most shot just fine. My cousin has a colt light rifle that has actual pieces missing from the rifling about half way down the bore. Still shoots 3 shots under an inch easily.
More than likely, the rifle will be fine.

I have several hammer forged Remington barrels that are quite smooth. I think most custom tubes are lapped after reaming and the rifling method probably has little or nothing to do with the interior finish.

A good hammer forged tube is notable for it's smoothness.
