as to the penetration problems and concerns, you can find ammo that wont over penetrate in about any of the lever gun calibers. If you live out of town a bit then standard loads are fine. they had a shooting in arkansas when i was there- the farmer defended his place with the .30-30 marlin,-hit the first guy in the hand- the second guy decided he didnt want to play. main thing is -shoot it, make sure its reliable, shoot it enough the action is second nature to you, be able to shove rounds in the loading gate without taking your eyes off target.. come to think of it, if you get that familiar with it, it wont matter as much which rifle action type you brought..
