I'm not excited about 350 myself but a buddy just bought one. He is shooting 150gr factory in Ruger BA and claims he is getting 1.5" in 3 shot groups. At 200yds he is claiming 3" with 7"drop from 100yd zero. He doesn't load and called to ask me if I would. I don't have the 350 dies. He is also telling me others are loading them with 9mm/ .356 bullets. The only advantage I can see in it is legal in straight case states and fits an AR. Pardon my lack of enthusiasm.
