I'm using the stock barrel with an Alpha434 Typhoon on the end. I was shooting at concrete tubes with a very slight crossbreeze( 2-4mph). My 2 longest targets are 285 and 320', cuz the concrete pieces are too heavy to move to 300' dead on.
I plan to paint some body size shapes on the tubes this week to be able to really gauge my shots. This past weekend I had a spotter down range with a mask, marking my hits with red paint for me.
I'll be sure to bring home lots of pics from D-Day for everyone. I'll also click a couple of pics of the first strike range that I'm using.
