the crown looks uniform aside from each picture being slightly tilted, and yes, the depth of the "grooves" in the area you note,appears shallow, have seen worse though....you sure its not YOU pulling off to the right? ( too much finger through and over, around the trigger) I would think looking at the pictures it would shoot high and left?? but I am NOT "ballistician", nor schooled in the art or angles, and reactions ( push off of the bullet leaving the bore and surrounding gas dispersion....) too many variables to consider and formulate this early in the morning.
a GOOD cleanup and check of the crown/bore, and being concentric you'd need the proper diameter 'spud' and gauge or a muzzle crown cutter to "check it out"..............as I said to ME the crown looks alright, just needs a good cleanup, put a piece of 3mScotchbrite pad across the muzzle and push hard with your finger in the center and go round and round, stainless is fairly soft and this is easy enough to do. The "bore" (lands and grooves, is NOT, needs to be recut?? see what Ruger asks or tells you to do.......just may be something "else" causing the "way right" :wink:
