I'm certain it was developed to fit certain state law requirements for deer hunting. Might even be a hit with .35 caliber or AR afficiandos, though I can't tell what it does that a .450 Bushmaster or .458 Socom won't do bigger and better (albeit with more recoil). Guess the .350 could shoot a bit flatter (arguably).

I've only got a .30 caliber can, so I don't have a dog in the race.

I'm too lazy to read that entire thread, though if anyone wanted to enlighten me, I'm all ears.
