I'm just barely getting to do testing with it and breaking in the barrel - so far so good - I've only shot 33gr V-max's to see how much fire formimg it will take, little to none so far. It feeds well so far, I haven't run a full mag through it yet. I haven't put it on the chrono, but I will in the next couple weeks - accuracy is sub-1/2 moa at 100 - it looks likeit's going to be a shooter. I hope to have it ready for coyotes this winter - are you interested in one?
