wondering on getting a 45lc for carrying in the woods for defense against black bear. i have come across a few in the past years and my daughter wants to tag along. i do handload . something like a cast bullet or a premium bullet do the trick on a 300lb black bear.
i already own 2 44mag's

I own both .44 Magnum and .45 Colt revolvers.
If you already have a .44 Magnum, I don't see the point in getting a .45 Long Colt.
You don't need a premium bullet. A simple semiwadcutter cast to wheelweight hardness will do the trick.
Frankly, the best close-up defense against black bear is a 16 or 12-gauge pump shotgun. It's what the Canucks carry around my cabin in British Columbia, where black and grizzly bear are common. Anglers fish streams with folding-stock Remington 870s and Mossbergs slung across their back.
The first load up is 00 buckshot, followed by slugs. The reasoning is that you'll be startled with the first shot, and need a little wider pattern to ensure a hit. Follow that up with Foster-type lead slugs (the classic slug).
The Canucks I've talked with aren't impressed with the Super Ultra Turbo ZX-500 slugs sold today. At close range, the classic Foster slug works as well, I'm told.
I keep my Browning A-5 semi-auto 12 gauge loaded at my cabin as above. I've never had a bear threat, so I've never shot one.
Keep things in perspective: If you have to shoot a bear, you'll be doing so at very close range. A bear at 75 yards distance is not yet an imminent threat. You'll almost certainly be shooting at 25 yards or less, so you don't need a super-duper bullet or slug to do the job, or minute of angle accuracy.

It will depend on the pistol you are looking at buying as to how you can load it. If it is anything other than a Ruger pistol you will not be able to load the 45LC to compete with the .44Mag. If you are looking at a Ruger pistol then you can load it to the hotter levels. I like shooting heavy hard cast bullets with a wide flat meplate. I have loaded in the past 300gr Hornady XTP bullets and they work ok but the cast bullets will penetrate like no ones business.

what he said.

I am going with the carry a 44 if you got it! But if you just have to carry a L.C then like was said go with Ruger Blackhawk or Vaquero,make sure the Vaquero is a old one...newer ones say NEW on side.There is frame difference between them,old models can be loaded to 44 pressures.

I use a Ruger Blackhawk .45 Colt with a 4 5/8" barrel as my normal handgun for hikes and fishing. It is easier to carry than my .44 Mag. S&W 629 with a 6" barrel, and with a good load it is quite powerful. It is a tough and reliable "little" revolver, and it is more fun to shoot than the .44 Mag.
