Hey all, first ever post. Will be going on my first black bear hunt in Maine over bait in Sept. 2014. Have hunted bear here in PA for years prior, but have never had a chance to see/harvest one. I'm extremely excited and have a question about caliber size. I've always hunted whitetails with my Remington 700 .270 Win for the past 20 years and love this gun. It's very accurate and I'm comfortable with it. Tight groups at 100 yds. Do you guys think the .270 Win is enough gun if I'll be shooting 150gr Federal VitalShok Nosler Partitions? I've looked around for a few used/new 35 Whelens in Remington 7600 Pump, but was unsuccessful. I would much rather use my ol' "go-to 270", but have been considering. Any other tips/advice about Maine would be appreciated. BTW I just joined and this is my first post. Thanks for all your input!
