Murph, a few words of advice. I don't think I'd be walkin' into the deep woods with a "rattle". As a fisherman, I use artificial lures at times with rattling BBs in them. Why? Fish sense the sound of the rattle thru their lateral line and are attracted to the bait. Bears have a very keen sense of smell and hearing, although their eyesight is a bit weak, but they can be very curious. The last thing you'd want is to be calling in the bears.

Remember that the common black bear is 6 times stronger than a man, so don't think you can fight it off. I've read that the recommended defense if attacked is to curl in a tight ball and play dead. Don't know if I'd put much faith in that either!
Second, I know you're older than me, and living in N.J., you'd probably be long gone by the time you finally cleared the paperwork to own a .44 Magnum. Additionally, the .44 has a fairly vicious recoil, requiring a solid two hand hold, and along with that, (after you've become proficient on paper targets), you would need to remain extremely calm to dispatch one very controlled shot into a vital area to stop a charging bear. There are lots of weapons that can kill a bear, but you don't need to kill it on the first shot; you need to stop it. Break the shoulder bones, or one thru the heart or head. Remember that cops practice combat shooting, (7 yards) all the time, but in a real life response against an armed foe, they're shootin' all over the place trying to defend themselves. (Adrenalin!!) There's been news reports where several cops fired a great many rounds, and the assailant was only hit once or twice. Forget the .44 Magnum.
Third, if you are venturing very deep into the woods, I'd suggest you carry a pocket GPS with plot charting ability, (and an extra set of batteries; they're tough on batteries). It's easy to get lost in the big woods, especially when it's relatively flat, as everything tends to look the same. If you can't hear cars or trucks on the road where you parked, you need to be able to get out and back to the car. As long as the GPS chart plotter is on and working correctly, you just put in your starting co-ordinates and follow the line home.
And last, you'll know you're in bear country if you come across a big pile of bear crap that has a whistle in it and smells like bear spray.

If you agree with the Progressives, it's freedom of speech. If you disagree, it's hate speech. There are no alternatives.
