300 win mag would be my vote - big enough for brown bear, overkill for deer and antelope
my accumark weighs around 9 1/2 pounds and i have a break on it so the recoil is no worse then a 243 win. and i have hand loads that will out shoot anything except a custom rifle and even some of those are out done. but hey thats why they make so many choices for us to have fun with
In my opinion, any 308 caliber rifle would be an excellent choice. A rifle chambered for the 30-06 Springfield and 300 Winchester Magnum are my recommendations. I personally use a rifle chambered for 300 Winchester Magnum for all my hunting. You would also have a large selection of bullets to choose from.
One of the most important pieces of equipment that you will take hunting is a good quality pair of optics and they take some care to give you the performance that you want. So here are a few tips.
Use some alcohol and cheese cloth to clean the lenses. I will usually pick up an extra cleaning kit from my optician when I have my eyes examined.
Don't touch the lens with your fingers. If there is a stick or a bug on them blow it off.
Use the lens covers. They are there...
