I could not have been happier. That rifle is zeroed and verified at 300 now.
I dont generally tell this story because of disbelief. So you can imagine how cool it was to see someone with the exact same situation!!
My A2 with Delton 1/9 HBAR that i built for Perry did not produce that but still did very well. I am guessing the 55gr really does well with 1/12.
I have never heard a single bad word about the AR15Sport.com "pencil barrels," whether 1/12 or 1/9. To get that one hole group with factory Fedreal Lake City M193 just floored me... I am glad your results were the same.
