I'm looking for a good all around gun from deer to moose including bear, and was wondering what you guys thought about a .300. i want a good long range gun that won't tear a whitetail up but that i could still use on something like a moose or bear.

Any .300 will work just fine...

Since you're a marine stud, I'd recommend a 300 Remington Ultra Mag.
Might want to use Barne's X bullets on the deer though!

I found the 300 Ultra alittle tough on deer,not as bad as the .338 ultra.
The 300 ultra is a good gun,and will kill anything you wan't.

I fell the gun that best suits ya is any of the .30 cal mag's or you might consider the .338 Win Mag.It is one of my favorites for all hunting.

For the hunting you are talking about I would look at the 300 WSM. The 300 Win Mag is a proven caliber as is the 30-06.

I would go for a .300 Wby. Mag., or .300 RUM. Good luck.

300win mag, 300rem ultra mag, 338 ultra mag, 8mm rem mag,338 win mag all great get anything calibers

I have killed moose bear and deer with a 7mm remington mag a 300 would do fine so would a 30.06 also.

.300 Wby. Mag. is great medicine from North American Game

After seeing deer shot with the .338 ultra by all means go get one it is the coolest deer rifle I have ever seen it flat knock's the $hit outa them.It was a enlightning experiance.
Then all bases covered no prob.From cockroaches to Africa anything inbetween.
