Wow I'm impressed, quality bolt gun accuracy from a Battle Rifle. You really should prove all the naysayers wrong by competing in the "2016 My Black Rifle Shoots Sub-MOA Groups All Day Long Challenge" here in the Black Rifle section.
Again wow, great shooting and without match ammo. no less.
While it would be nice to discount a flier from time to time (or in your case almost every time

) as it sure would tighten up all our groups; a true measure of a rifles accuracy (and the shooter's) is to add up all our inconsistencies. As it's the only way to truly know if we're improving.
Perhaps try over lapping all those #5x5Rd. groups to see what you and your rifles real accuracy is? (Yes, this is a fair way to determine accuracy).
Ever thought the consistency of a having a flier on #4 out of #5 (almost every) group(s) was something more then shooter error? Like perhaps was relatable to the firearm?
Seriously it's good to hear the OP is happy with their purchase and Wolverine rock as a distributor/supplier, but it has to be said these rifles are typically a 2"-4" MOA semi.-auto. battle rifle using premium ammo.; not a 1/2" MOA capable match grade semi.-auto. rifle.. Because if that's what people expect after their +/-$3,000 purchase their in for a rude awakening.
So many times it's stated regarding XCR rifles that if it wasn't for that one flier it'd be a MOA rifle or even Sub-MOA, however that's the problem with these rifles they have difficulty maintaining REPEATABLE accuracy (which like it or not is the true accuracy of any firearm) due in large part to the barrel retention design.
I'm only trying to make aware the true accuracy potential for anyone considering a XCR, as buyer's they need to know what they're getting themselves into when spending several thousand dollars on what is a Battle Rifle designed to hit a man sized target out to 300-400 metres, not clay pigeons.
To all those who say I'm anti-RA XCR rifle I say no I'm not. What I am against is one of our CGN members spending a large chunk of their earnings on a rifle they expect to shoot MOA or better when that's just not a realistic expectation (MOA or better is just not attainable for all, but the most accurate semi.-auto. rifles) for a mass produced battle rifle.
