Wow... The ol' .30-30.... [8D]

A timeless classic. Probably dropped more deer over the past 100+ years than any other cartridge with exception to the .30-06 - maybe.
The .30-30 is a 150 yard gun. Maybe 200 but that's stretching it, even with the Hornady LeverEvolution. It's best used in the heavy woods and thick brush, where it's quick to come up on target. The 170gr rounds are fine for deer and bear (depending on the size of the bear), and will also drop a coyote instantly with 150gr rounds.
Some guys put a scope on the .30-30,others (like me) don't. I did have a small 4x32 scope at one time, but took it off. It just didn't "look right" to me. Putting a scope on a lever gun is like putting hiking boots on a ballerina, you know? I can be done, it just doesn't look right.
{just my opinion folks, just my opinion....}
If you want a do-everything rifle for coyote, deer, bear, and boar, I would look past the .30-30 and get a .270 or .30-06- maybe even the classic .308 round.
Don't get me wrong, the .30-30 is an excellent round - as long as you know its limitations and stay within them. I love my .30-30 and only use it in the thick brush on man drives, if I happen to jump a deer. For longer ranges and different situations, I use my Savage .308 with scope.
