This rifle isn't quite ready to go shoot yet, but within the next few weeks I plan on testing the trigger reliability using various types of ammo that I would typically encounter, including Prvi Partisan, American Eagle, etc. I also have a few thousand rounds of Georgia Arms "canned heat" left over from several years ago, both in SS109 and M193.
Not to beat a dead horse, but did anyone else here besides septic-tank13 and Shihan have issues with Prvi or other surplus / military ammo, using the stock Timney trigger? I'm just interested in how common this problem is... Timney seems to partially admit that the trigger was not designed to fire military ammo, but they also say it "should" work. Either way I'll probably end up with putting in the AR10 hammer spring for peace of mind, but I first want to do some more testing and perhaps add to the sample of evidence...
