Assembled my first AR with PSA parts last month. It's a 16" with a carbine length gas system. After running several hundred rounds of FMJ factory and reloaded ammo through it I wanted to move on to cast boolits. Managed to catch Midway with some Lee 55gn molds in stock so I thought I'd give those a try before committing to a different mold and heavier boolit.
These were only out to 27 yards, it's a start, but I plan on mounting a scope and moving out to 50, 75 and 100 yards next time out. The 2230 loads cycled fine, but 4227 12.5gn load only cycled twice out of the five rounds. The orange target stickers are 3" by the way.
