    I stripped it today and cleaned with BT C4. Helped a bit, but not a ton. Had to order some fresh paste. when I use jb bore paste, what size brass brush should I use, regular 0.308 or oversized to a 0.338?

    Thanks to all for the replies. It was shooting 0.5-0.8" @ 200yds for the first 100 rounds. The last 20 were closer to 3-4" groups. The spent case was sticking in the chamber, not the bullet. Also large ejector swipe and flat primers for the last 20 rounds.

    Brand New rifle. I scoped it before ever shooting it, and it was definitely a new barrel. Anyone else with a 300prc seeing similar results? May be sending it back to the smith....

    Thanks @Bradu. Was going to try wipe out but I also have jb bore paste. Never needed it so early in a barrels life though, so hesitant to pull it out yet.

    It is not shooting, that's the problem. Factory 225 ammo started showing pressure signs and stuck in chamber after 115 rounds. Trying to diagnose what could be going on

    Thank you for the all the info and detail! It is a 300prc with only 120 rounds (100 factory) down the barrel. Doesn't look pretty, which is my concern

    I recently purchased a Teslong Borescope and regretfully there is not a library of images on google to compare my barrels to. Please provide any and all feedback on what I am seeing in the below images. I am intentionally leaving out round counts on the barrels to not bias anyone's answers...

    The Target paper is 110lb stock, so pretty durable. I will keep a lookout for any future tears of this nature, etc.
