I could bring my Ruger #1 .270 - haven't shot it in a couple years. Last time I had it at the range I was shooting other stuff at 50 yards. I decided just to check zero on it, and after 3 shots there was one caliber-sized hole in the target. I was a little concerned and raised the POA an inch. A new hole appeared exactly an inch above the other. So with a 10x scope at 50 yards the first 3 shots looked like 1 hole
