Trying to help a friend out. I hope I am asking this right. Anyone know the SAAMI technical specs (width & depth or width and height) of the lands and grooves for a 22 magnum?

    think you are going to get bore and groove diameter w/specs. only. a guess at the bore is about .218 and groove about .2225. there will be a tolerance too- I don't know-maybe a .0002
