As some of the others said, you may have to try different brands to get accuracy. I have a 99 Savage and Winchester and Federal shoot unbelievably bad in it.(6-7 inch groups @ 100 yards) The Remington Core Lokt .243s shoot a 3 shot group you can cover with a quarter @ 100 yards. The others are way too hot for a lever action and make the bolt sticky when you cycle the gun. Anyway, I have done good on white tails with Remington .243 ammo.
