Sorry for the double post, I didn't think the first one went through

i have some 180 gamekings layin around. they worth a try? ive been using them in the 30 06. will these provide good penetration on close shots. i know i ask that alot but i would hate to wound a deer or have it run a long way. thats one of the reasons im usin the 300 to start with. thanks

But does it blow fist size holes in the deer?

OEH,
No way, for fist sized holes I need my trusty 243 or 22-250.

I used the 300 Win Mag back in my rambo days. I would recommend 180 grain bullets for everything in the 300 Mag. Maybe for the big bears I would go with the 200 Grain Partition. The 180 grain bullet tends to do less meat damage bcause the jackets are a bit thicker. Its a good all around big game rifle to much recoil for the old magnum battered shoulder now adays but ok for not yet shot out shoulders.

I would also reccomend 180's for most shooting, as they seem to shoot the best out of my gun. I do want to try some 220's though

if u had a choice between tryin the 165 patrition or hornady interbond what would u try. ive read ALOT of good things about both. thanks for the help guys im really learning

I'd use the Nosler.

I'll 2nd that motion! But, what about the Trophy Bonded bullets from Speer? I think I'd
rather use it than either the Hornady or the Nosler.

Duke, Like some of the guys are saying, the 150 may be too 'tender' as they put it and may cause a good bit of meat damage, particularly if hit in the shoulder. If your worried about meat damage, try to avoid the shoulder and shot just behind it or, if close enough, a neck shot (except if you want the mount). A shot just behind the shoulder with a 150 gr bullet at 3000+ fps will cause horrific damage to the lungs and the hydroshock will be substantial.
If your shots are mostly out there at the 300 yd mark, I would go to a 180 gr bullet. I load my 300WM with 72 gr of IMR4350 behind a 180 Sierra Pro Hunter and a Rem 9 1/2 magnum primer.
