Mike,
Before you pull out your wallet and start throwing good money at a stockmaker, as him if he has a try gun. If he doesn't, you could end up paying a lot for wood and stocking for a gun that may not fit you at all, and with which you may not be able to hit a thing.
Stock fit is an individual thing, none of us are the same size shape, as the next man.
A try gun will determine in advance the amount of cast off or cast on, of the butt stock, it will also determine the correct drop of the stock and the length of pull. There are average measurements that are used by manufacturers but there isn't one size fits all. If your paying for a new stocking of your shotgun you will want it to fit correctly.
