I bought a Teslong borescope a few weeks ago and this is what the bore looks like in my son's Remington 700 Magpul Edition in .308. For some reason, I've always had a hard time getting this gun to group better than 1MOA with any load I try and I'm pretty sure I found the reason why. From what I can tell, these marks were caused during the actual button rifling process even though I thought these 5r barrels should have been hammer forged. So do you guys think I'm right to assume that these chatter marks are causing accuracy problems or are they normal for a factory barrel?
