This is a US made copy of the German G3. My nephew bought one and we shot it last weekend with factory ammo, not sure what brand but was new, non corrosive ammo. We considered reloading for it but examining the brass were surprised at how much damage the rifle did to it. The marks from the fluted chamber were relatively mild but in the ejection cycle the cases hit the ejection port and were dented badly. I have had dings on cases in my M1 from hitting the op rod but the dents his rifle puts on the brass were so bad it looked like you hit them with a hammer. Far too damaged to even consider reloading.
Wondering if any forum members are familiar with the rifle and is there some way to adjust port pressure to reduce the violence of the ejection cycle.
