Re-barreled a rifle to 260 Remington, barrel is a 26" Shilen stainless.
Towards the end of my shooting session today, noticed that the bolt was getting tough to unlock and extract the spent casing. When I did finally get the casing out, I noticed these horizontal rings going around the entire case wall. (Photo isn't the best, but you should be able to make out the rings.)

The spent rounds showed no evidence of being over-pressure, and the rifle was shooting consistently.
The barrel has less than 300 rounds down the bore, and this is the first time it's exhibited those rings on the spent casings.
Any ideas??
