I have the Remington 799 (I think) which is the Zastava and I can't get it to group well at all. Played with quite a few bullets and best yet is about 2" at 100 mtrs using Li'l Gun and 40 gn Sierra Hornet bullet. The worst is unbelieveable over 20" at 100 mtrs with Li'l Gun and 52 gn SMK. I've just ordered and received a bunch of other 40 gn bullets and now it's time for another go around. I just have to let my frustration abate a little more before I tackle it again.
