The 35 Remington is like the big brother of the 30-30. Able to sling a heavier bullet it delivers more energy than 30-30. The Hornady ammo has the plastic tip so you get better aerodynamic performance but it's safe to use in a tubular magazine. There is a chance that pointed bullets can set the next one off in the tube. The Remington Core Lokt rounds are just hunting rounds. Will straight fuck up a deer, hog, or black bear. The buffalo bore are just hot loaded with a heavy bullet for extra punch.
