You can use spitzer types in the .30-30 lever gun but you will have to single load them into the chamber. That bullet point up next to the primer in the magazine tube could make things exciting. The disclaimer done, I do load 125 grain Remington Core lokt in the .30-30 as well as the single shot pistol bullets for my Contender and have tried them in my Winchester 94 to see how they'd do. While I have not, others have loaded the 168 grain match grade hollow point round to play with long range targets. The lighter bullet shoot flatter and are adequate for whitetail deer. I didn't chronograph any loads but my data suggests the 2400-2500fps range from 20 inch barrels.
