I did get to the range. I was trying the rifle buffer with weights removed along with a CAR type buffer spring. I think I am on the right track. The 9gr loading works fine now, but still is supersonic. around 1180 fps I think. I tried a loading of 8grs and it failed. I have no pressure signs at all, the primers almost look as if if were a empty cartridge, everything very rounded. Since I am getting proper cycling with low powered rounds I am assuming the gas system is fine. The magazines all work well, no problems there. Well, not exactly. I was using some brand new C-products but it seems the spring might be a bit stiff so I switched over to some old, well used orlites I had sitting around, they seem to need less effort to strip a round and still feed just fine.
I haven't worked with any higher powered loadings yet fot two reasons. First is I haven't got my adjustable gas tube yet (Waiting for it to come off back order) and second is that I want to get the subsonic hammered out first.
All rounds have ejected properly, it is the short stroking I am trying to work out now. My next step is to take bolt cutters to the range and try it all over again clipping off a coil at a time until it functions properly.
BTW, ammo is as follows, 200gr hardcast w/gas check over various weights of WC820.
I also have some WC680 do you think that would be a better powder to work with?
