That's a good way of determineing accuracy, since it keeps in mind the old fashioned idea that it might matter if you hit what you're aiming at. Laying a first cold bore shot where it belongs is another.
I get a kick out of watching shooters with a nice tight group three inches high that they can cover with the appropriate coin, and a notation marking the first shot somewhere other than in the group. (Not that they sight in for it, but apparently they know about it) They seem to have covering a group with a dime confused with being able to hit a dime. It's a little hard to hit that tiny target at say, 200 yards from a bench while trying to aim 4 inches below it. That's OK, they will explain, since 4 inches is SFA on a big-game animal. Hmmm.............. a 4 MOA rifle will keep the worst shots within 4 inches of point of aim too at that distance, provided it was zeroed for that range. Come to think of it, unless the dime shooter is putting them all in the same hole, MR 4 MOA is going to be closer over half of the time.
