I've had it to the range several times, and it runs very nicely. I still need a magnified optic for hunting. I probably won't pick one out till summer.
I plan to work up a handload with Barnes 95 grain TTSX for hunting and barrier penetration. For softer targets I guess I'll use Sierra 110 grain Pro-Hunters. I'll probably use Reloder 10X for both.
