Well, took the Freedom Machine out this morning to see how she likes the Prvi 175gr FMJBT. I'd have to say she was loving it! Until she just quit working. :o Trigger won't move. Oh, must be the...nope, safety is off. Drop magazine, clear chamber, lock bolt back. Drop bolt. No clicky-click. About then I see a twisted piece of brass. Upon closer examination, it is an anvil from a primer (shooting off the hood of my Ranger, usually there isn't any anvils on there). You have GOT to be kidding me I'm thinking, having JUST read an article yesterday where a primer jammed up the trigger group on an AR15. Pull the upper off the FM and sure as poop, the primer cup is down in the trigger group. Squeeze the trigger, primer is blocking it. Dump it out, trigger works fine catching the hammer with my other thumb. So now the search begins for the offending cartridge that lost the primer. Found it...nice once fired brass with the primer missing. Anyone try the clear nail polish to hold the primers in place? Jon
