I've been shooting Mylasian surplus that I picked up on the cheap out of mine and it's been nothing but reliable. It's certainly not as accurate as Federal Gold Medal, which is down right surgical, but comparing surplus ammo to Federal Gold Medal is like comparing a V6 Mustang to a GT500, no comparison. The surplus is fine for punching holes in Q targets from 100-300 yards, but if you want to put holes inside of holes, the Federal GM is my hands down winner. We use "off the shelf" Federal Gold Medal exclusively in our SWAT team sniper rifles, so obviously its passed the most stringent of consistancy and reliability testing, but it aint cheap.
Liquid, those VEPR's are gorgous! I remembers seeing a picture of one of yours that had what looked to be a Kydex adjustable cheak weld adapter on the stock, any information you could provide about that?
