i've hunted the va. wva. mountians on and off for 30yrs. mostly a meat hunter. this fall had a close incounter with a fairly large black bear i've glassed them but never been in smelling range. i have to say i've never been on edge like that on a hunt in my life. now i'm hooked. i had my270 with 100 grs partitions and was afraid i'd just maim him. so my question is what is a a good caliber and load(i reload) for brushy 150 yrd shots? i have a 3006/270/ and a 6mm rem now but wouldn't mind building a dedicated bear rifle thanks
