[QUOTE="tankgijohn72, post: 1485812, member: 77441"] Shoot whatever loads you had that were grouping 1". Those pressure signs aren't bad. Are your bolt lifts heavy? If not, you are probably good to go. My guess is that Remington ran a finish reamer into your chamber. I had a 300 WM that I had to send back to them because it had very tight chamber, and that's what they told me they did to it. After that I had zero issues. (Agree with someone else that unlikely to have tight freebore. No Remington barrel I have is even close. My 308 is near a quarter of an inche). Brass shavings in the chamber/bolt face area can be very common with belted magnums. As you chamber a round the case runs over the sharp edge in the chamber recess cut for the belt. I load and shoot .243 to 35 whelen and there is always more brass on the 300 WM than any other cartridge. [/QUOTE]
