HWR quantifies "moron" guns. Actually, HWR is the radius at which the gun's concentrated weight would produce the measured MOI. It is in inches and I will start to add that dimension. It is useful as a comparison among guns as to the individual guns' weight distributions. Guns below 10" will have lower MOI than the weight suggsts. 10" to 11" is typical. Above 11" and you have a "moron" gun. Those who shoot clay targets like "moton" guns as witnessed by the HWR's of the K-gun, P-gun, and NID-gun posted here.
Does that do it, or do you need some additional explaination?
