for personal protection, i use one of my .45 ACP's, loaded with 230 grain hydra-shocks. my fav is the kimber, but the commander is a very very very close second.
i also have a 7mm Rem Mag. love it. its a savage, heavy bull barrel with an on/off muzzle break. black synthetic stock. cost all of $280!! beats a 30-06...although i'm not trying to trash the ol' '06. but the 7mm goes further, faster, flatter, and with more UMPH.
i also have a 45-70 marlin guide gun. DAMN, cant wait to take a NY whitetail with that puppy. there was a 2 part write up on it in "rifle magazine". they took it africa. it went through a zebra diagonally...about 5 feet worth. but that aint nothin' yet. they stalked a cape buffalo bull(approx 1600 lbs) as he walked to a herd. when thy spotted him, the dude took a shot, broadside) at about 100 yards. penetrated both shoulders(the bones my friends), and went into the cow cape buffalo that was 5 yards behind him. went through her shoulders(again, the bones) and lodged under her skin on the far side. i hope if i take a whitetail with it that i'll still have some meat left.
have a nice day
