But if you mention pointed bullets and 30-30 in the reloading section watch the guys freak out about chain fires before you even mention single shot or bolt action.
I won't freak out because of an experiment I did many years ago. I took a remington 150 spitzer pointy bullet and primed a 30-30 case and drilled a hole in my work bench for the case to fit into.
Then I held that "pointy" bullet with a pair of pliers and placed the bullet against the primer and hammered away. I beat that bullet up so bad it had to be thrown away. I never did get it to set off the primer in the case. I then took the primed case and dropped it in my marlin and fired it to make sure the primer was still good.
So I don't worry about pointed bullets in a tube magazine. Like gunplummer stated most pointy bullets are designed for higher velocities anyway. But you can get lighter weight spitzers designed for specialty pistols like the TC contenders that will work at lower velocity. But most do not have the needed cannelure and on some the ogive will be inside the case mouth to keep the OAL so the round will cycle in the action.
Besides if you think you need the extra range a spitzer will give then you will most likely need higher velocity to go with it. And the 30 Winchester lever guns are not about long range. They are about light, handy guns with rounds suited to 200 yards or less. But they can be used at longer range but you will need a scope or better sighting system for a humane shot on game. My bud killed a deer just over 300 yards away but his 30-30 Marlin has a Leupold 2x7 scope on it. He held just over the backed and killed a buck with a back of the lungs hit.
