Either of the bullets in the calibers you mentioned will work. Black bears aren't all that hard to kill, but you do want something that will penetrate through and through while still giving good expansion. Nosler Partions are a great choice and I will be using them on my bear hunt next week. I hope you have a great hunt.
I'm hunting Saskatchewan black bear May '08 - use your BOW
Everyone I've talked to says that black bear (over bait) is a definite bow hunt. Provided, of course, that one is proficient with a bow (min. 160 lb. draw / 125 grain non-mechanical broadhead).
From what I've researched, many good options on rifle for black bears - 30-06, 7 mm magnum, 300 mag or 300 WSM plenty powerful - should be at least a 180 grain - nosler partition a good choice. I like the Accubond round personally - took down a 1,200 lb. moose in 2004 with one well-placed shot.
Like most of you I'm certain, I love to shoot my guns. I enjoy shot after shot all day long at the shooting range… whether it is with one of my Shotguns, one of my rifles, or with my handgun… or when the crosshairs are on a big game animal in a safe shooting scenario. I love to shoot! What I don’t have the same excitement about is cleaning my gun afterwards.Now this is not going to be gun cleaning 101 as every kit comes with its own set of directions and the internet also has a great deal...
