i've already said this on another forum but i would have to say the good ol 30-06. you can use the accelerators on varmits and small game, the 125s to 180s on antelope to elk, the the 220s for everything else in north america.

What about the 270 WSM? A tad more powerful and flatter shooting with a bit less recoil than the 7 mm, plus you will have the lightweight, short action gun.

IMO the 7mm is the best "all around" caliber made. I personally own a 7mm Mag and a 7mm RUM. I enjoy both and have hunted Antelope, Mulies, Elk, Moose, Bear, etc. It will handle anything and give you solid performance when hunting all types of big game. I would recommend the RUM if you reload (a must for the RUMs) and are looking for a just a little flatter/more energy version of the 7mm.

How about a Remington 7mm-08 Mountain rifle. My dad has one and he loves it. I took it to hawaii on an axis deer hunt and I really liked it.

I have a Browning A bolt in 300wsm. Shoots amazingly well. 1/2 MOA consistantly. Shot one group of three at 200 yards that were all touching. If you reload my combo was 200 g Nosler partition over R19 (PM if you want the charge weights). Also worked a load for it with 150gr. seirra game kings. Didn't shoot as well, only 3/4 MOA . Great gun, great round. FYI I also own a winchester M70 in the 270 WSM, Its a fine weapon as well.

The WSM line that I've shot are very accurate. For what you've described I would suggest the 300 wsm. Its a great round. The exploits and versatility of the 30 Cal. bullet are well documented. But, the 7 mag would be an excellent choice as well.
