Really looking forward to getting this upper in. Along with some ammo and two Mags. The 350 is a long straight cartridge case. Making it legal to hunt deer, etc. in many states that do not allow bottle neck center fire calibers. But the Midwestern States do allow this one. https://winchester.com/350-Legend Federal and Hornady also produce ammo for this new caliber. https://www.federalpremium.com/rifle/power-shok/power-shok-rifle/11-350LA.html So, I ordered this Saturday. BCA complete upper on sale for $249.00. Now, I can start hunting my favorite trophy buck spot and not be limited like with my 12 gauge. The 350 seems to have a lot of foot lbs of energy per the Winchester charts above. Ammo is so much cheaper than a 450 or larger. No comparison on cost. I will be using the 180gr soft point ammo for hunting. This is not one for just plinking, but for hunting in my state of Iowa.
