I run an XCR Compact. Tac. in .223 it shoots the 50gr-60gr vmax's well, my only complaint is it gets a little heavy for a carry rifle, and its muzzle heavy, could be due to the fact i put too much glass on it. also the B&C stock has an aluminum bedding block in it and my POI shifts about 3-4in from summer to winter. but it will hold .75MOA, and sometimes it will shoot .5
