Using shotgun butt "shims"

[Ufatz]

I'm puzzled by the talk I heard about shotgun "shim kits" that presumably allow you to change what I've called "drop" all my life, and also adjust "cast-off" or "cast-on" to a shotgun butt. I'm puzzled at how they would work, without making the gun double-ugly i.e. with stuff sticking out all over from the butt plate. What am I missing? How do they work? Can you actually change the fit of a shotgun with one of these kits?? Doing serious changes to pitch, drop, cast etc. used to be a time consuming challenge. So, what sthe deal?

Never to old to learn something new!

Most shims go between the stock and the reciever instead of off the butt plate. A shim can make a worlds difference in how your gun pulls up.

Diddo what rost said. My Benelli M1 has the adjustable shim kit that fits between the stock and reciever and a little bit goes a long ways. Picture how you want to be looking down the barrel when you shoot, then shoulder the gun with your eyes closed. Open your eyes, and if the gun isn't where you want it, odds are it's not a proper fit. Then the trial and error starts.
