which rifle cartridge to use?

.300 RUM, :2guns

RCM???

really, IMHO the smaller calibers (.223 ,.243 ) will get the job done, BUT shot placement is very important. Really, how much do you want to spend on ammo? that is one of the deciding factors. the 30-06 has been killing stuff for a long time. also have alittle more selection on bullet weights in 30-06 and 308. .270 only has a few bullet weights to choose from. i hunt with 130 grn. hogs and deer. doesn't matter what you are shooting if you make a bad shot. the only round that has alot of forgiveness in shot placement is gonna be the .50 BMG. lol

really, shot placement is very important. l

WHen all else fails take 2 to 3 shots at it til it drops. :rambo

243 :rockon

In all actuallity,my .358 pretty much is the baddest MF in town. Nothing walks away from a hit,even a Texas heart shot.Ass shot,gut shot,head shot whatever,it's done.
