Both will do the job if they hit the right spot. I had a friend who shot a 120# mountain lion that had been struck twice by .45 ACP hollow point rounds and still had an incredible amount of fight left in him. Bigger and faster is always better but shot placement reigns supreme.
357...JSP Vs FMJ

I can't explain how, or why, but the heavy for caliber hardcast bullets offered by Double Tap, Buffalo Bore and others including hand loaders will significantly out penetrate either FMJ or JSP. I've seen test results showing 147 gr 9mm loads with these bullets penetrating 60+ " I say 60+ because they only had 60" of gel and did not catch the bullet. You see similar things with all other cartridges using those loads. With conventional JHP or FMJ we're looking at closer to 24" of penetration, often less.
If I were carrying a 357 mag where bear were a concern I'd use 180 gr bullets minimum. A 180 or 200 gr JHP would work just fine on "average" bear. If in an area where bigger, or more aggressive bear were a possibility I'd feel a LOT better with the hotter hardcast loads.
A HP bullet that is heavy enough to still give good penetration will kill quicker. I don't think 158 gr is heavy enough at 35 caliber. When you get to really big animals, especially with smaller guns you give up on expansion and go for all the penetration you can get.

If you are looking at 158gr JSP bullets, IMO, there is only one; the Sierra JSP.

There is enough exposed lead to give some expansion and it is effective (and accurate) at a wide range of velocities. One additional benefit is that it is shallow seating for its weight.

What repressive state are you in? I'm in CA, and we cannot order online either, but I was able to find a dealer who put in a special order for Buffalobore ammo since they are one of their suppliers. You can also have BB ship to one of your FFL's.

I don't have to read the article. If his argument is that the shoulder of a SWC doesn't do anything because I proved it by filling it with grease to make it smooth -- that's what we call "dumb."bamaranger said:
It probably involves one of more logical fallacies, but I'm much too tired to look up which one(s).

On hard cast, I've never read a single post of someone recovering a deformed FMJ from any tested material other than a rock hit round dug out of dirt.
If a copper FMJ doesn't deform even on bone, what does hard cast different? Absolutely nothing at all. In fact, hard cast can fracture/shatter.
Here's a Hornady bullet advertised with a thick copper jacket so it won't deform:

Back from a long absence . . . . .
Some may have missed me or just as soon I stayed away
Anyways
A 357429 cast at about 18-20 bnh on top a healthy dose of 2400 will take care of badduns'.
