Seriously I wonder why use a 30-30 TODAY instead of a 308 Win. I understand liking LEVER action rifles, light, short, fast handling. There are 308s in LEVER actions & IMHO they are in higher quality guns, some have rotary mags, some clips, & most of the time better accuracy.
I AM NOT TRYING TO START ANY ARGUMENT or BLAZING FLAME!! We have enough of that going on NOW.
If you NEVER cross an open field or pasture, pipeline, powerline, etc. I guess you don't need the flatter trajectory and higher retained vel. & energy of a 308,7-08,243. With a 308 you still have 30 cal. holes.
These are my thoughts & questions. Why 30-30, NOT 308?
Well, you did a good job of it by asking a silly question. Sometimes it's worth asking the question of yourself before punching the enter button, perhaps rephrased: What will a .308 kill that a .30-30 won't?
