Nothing wrong with that barrel. That's not a liner just a clean crown. Should be kept that way for best accuracy. That is the last part of your barrel when the bullet exits, if there is a ding on that crown your accuracy will go south. So keep it that way, be careful when cleaning, bringing the rod back through the barrel don't ding that crown. The 700P is a Very accurate bolt action, with the 40x trigger, that is not standard, That's a fine tuned rifle. Keep it clean & enjoy shooting. VERY NICE RIFLE. Be Safe, Chris. What caliber is it, 308 or 300 Win Mag.?
