Thinking about adding an XCR to the collection, and was wondering if some owners and/or those familiar with the design could provide some information on how the XCR runs with heavier 5.56 bullets.
From what I see on Robinson's website, the XCR in 5.56 is only offered with a 1-9 twist rate. My two existing 5.56 rifles are both 1-7 twist, and I prefer running 77 grain ammo through those. Having to stock two different bullet weights in 5.56mm would be almost as much trouble as stocking two seperate calibers, so I'm thinking the potential purchase probably hinges on how well the XCR/1-9 twist combo does with 75-77 grain rounds.
I'm not necessarily looking for a quarter-MOA bench rest or uber-mallninja performance, but just wanted to verify the XCR delivers service rifle/patrol carbine acceptable sort of accuracy with heavier bullets.
