I just picked up a Remington 700 XHR 7mm Mag and took it to the range for the first time today. I got it sighted in and it shoots great, but I noticed a couple of deep scratches up near the neck on each piece of brass. This may be nothing to worry about but thought I would ask here before packing it up and sending it off to Remington. One of the range officers told me they would go away after time, but in the meantime it is making me a little leery about reloading the brass fired in this gun. Is there a way for a novice to polish these burs or should I send it back to Remington and let them polish it properly? Thanks for your help!
