I built one on a stiller Diamondback drop port as a live varmint and ground hog match rifle. I've taken G-Hogs over 700, a fox at 670 and and had it with me while doing crop damage, so I took a deer with it and then another and another.
It works fine and has it limits, it is so accurate it can quickly get you in trouble by shooting farther than it has energy. Ive taken many deer between 400-500 and some much farther but would not recommend that. keep it within reason and it will be fine. For a primary hunting rifle I would go larger.

Has shot some great groups, this is my best prone.
