Some interesting comments. Rocketman's approach is the one and only truly good engineering approach I've seen to quantifying the gun's characteristics. Lowell's comment gives praise to those great gunmakers of the past that emperically developed some really great handling guns. John Mann's comments acknowledge that men are all built differently and thus a given gun's characteristics will be percieved differently by different people.

Builder, I think what you were experiencing with that K80 was that the MOI was relatively low for the gun weight. That could be due to a short stock or short/light barrels or both. Two identical guns but for their LOP will have different MOI's and therefore different "feel"/"swing weight"/"livelyness" or whatever the favorite buzz word is.

One thing I've concluded for myself; I like different MOI/overall weight guns for different applications. What produces the best shooting is not necessarily what I want to carry up and down steep hills all day long.
