I have the newer rotary box mag version, not the tubular magazine version. The action is very similar to an M-1 Carbine/mini-14.

Accuracy wise, using the stock peep sights, a pop-can is dead at 50 yards or less. It has killed 3 deer and a few coyotes. I prefer 240 grain JHP full tilt pistol loads. Usually H110 is the powder I load, or Win 296.

It shoots the 300 grain bullets just fine. It is a fun gun to shoot. Just wish someone made higher capacity mags for it, as they only hold 4 rounds +1.
