With ammo being so scarce, I have only been able to try out a couple different types of ammo since I put this one together. Today I found some cheap Monarch 123gr hollow points at Academy and gave them a try. My Ruger American Ranch didn't care for them, but my Bear Creek upper really liked them. I need to go back and buy more now. Some people like to rag on bear creek, but it's hard to argue with those results.
