After taking the weekend range session I took the gun down (700ml) and cleaned it. I got curious to see if I had any crush to the Fed209A primers after the cleaning session. After testing 3/4 primers there seems to be no crush. In the back of my head I am always concerned with blowback being a left handed shooting. If I remember right I am getting a crush fit with my other 700ml and Fed209 primers. The O-rings I've come across searching the site seem cheap enough, but wanted to make sure their was no negative effect of using one. Fed209s are all I've ever shot in all my 700mls converted and unconverted. I am using Arrowhead 209 bolt nose kit and plugs. TIA.
