Check the Remington website for an authorized repair center nearest you. I would take your receipt and the gun if there's an authorized gunsmith in your area. You could have an excessive headspace problem or simply got a bad lot of ammo that is loaded too hot. I've had both happen with hot ammo from winchester in a 25-06 and excessive headspace on a Remington 700 in 257 Roberts.

If you do have to send the rifle in to Remington you won't be getting it back before October 15th unless you are extremely lucky. The Remington I had to send back(257 Roberts) took about 7 weeks to be returned.
