I have no experience with any of the listed cartridges but, based on reading, the 350 Legend looks like a good choice for deer in light and short rifles. For bigger game (scary big bad bears) in densely wooded areas, I would probably go with a 500 Smith and Wesson magnum if strait wall was mandatory, but I don't know if it is legal in the strait wall states. That cartridge appeals to me because I have seen the .50 caliber's work from my muzzleloader and I sure liked it a lot: 295 grain hollow point over two pellets of Triple Seven is simply perfect for deer. The only rifle I know of which chambers this Smith and Wesson cartridge is the Big Horn Armory Model 89, a nice looking but expensive lever action, or a new barrel for my Encore, which could be a future though, maybe. I wish I knew of a bolt action rifle so chambered, it could be an interesting item.
