This is apparently a new cartridge on the skyline (Shot Show presentation) for those states (i.e., Mich, Iowa, Indiana [?] to name a few) allowing straight-walled cartridges for deer hunting of late. The .350 Legend as I understand it is based off the .223 and opened up to .357 and with the same COAL. The ballistics for a 150-gr FTX-type of bullet zeroed for 150 will give you a hold-on for deer to 200. It’ll be priced similarly to the .223 ammo but will exceed its energy significantly (1800 ftlbs vs 1200 ftlbs, I presume at the muzzle).

This will be another option for those who forego the charcoal-burners, shotguns, the 450 Bushmaster, or handguns. Sounds interesting.

It’ll be a candidate for accurate bolt guns and I imagine AR uppers are in the works somewhere. Read more at:
