.357 is great in the Spring but not so great in the fall with all that winter fat getting in the way. A bit confused as why anyone considers cost really... How many bear do you expect to shoot? If you are looking the best you can get to ward off a bear consider throwing a small sport air horn in your pocket. Bear have twice the hearing as humans and that sound is piercing and will always send them running. And yes I have used it. It's always in the UTV and the wife carries one on her walks in the woods. Calibre wise. 45-70 Gov stops the stubborn ones in their tracks but, yes, its an expensive choice.
The cost factor is in reloading. Essentially for my "need to have" guns for hunting are these 5, and all need to be affordable calibers where possible because I do alot of shooting like most folks on here and even though I make a pretty good paycheck and support a family of 5 on it, I need to operate leaner even in hobbies to save money where I can.
1 - around the house plinking gun for squirrels, skunks coons etc and just fun plinking. Currently a henry 22
2- brush gun, always been a 3030 with a 20" or greater barrel, and although it's kind of perfect for nova scotia I'd like a lighter, shorter barrel to get around with. I hunt really light and compact and i've had a 357 before and loved it, regret getting rid of it. currently using a henry model x in 3030 but also have a pre 64 model 94 and a 336 Marlin all in 3030
3- longer range gun for corn fields and such, or hunting fields in NB. Currently a tikka t3x in 243
4- Hybrid gun for forest/field - have an old beater savage 99F with see through mounts so I can bust brush or jump up to scope for longer shots
5- A shotgun for small game. I don't go after ducks or geese yet, no dog or boat etc plus I like chasing game around the woods looking for new trapping spots. I normally use a break barrel winchester 37A (I can't tell you why, but I love these guns!) but have a lot of shotguns from SXP, to canucks, to cooeys etc.
