There is no need for more than standard factory ammo from Remington. I like the 250 grain PSP load if it is still available out there. I have two cases and haven't bought more in years. The nice thing about a 250 grain bullet at 2400 fps is that you don't need more than a factory Remington or handloaded Speer bullet. The Double Tap and Nosler ammo are excellent insurance for an expensive hunt, if you are away from home.
