TS - the magic is between you and the Mossberg. I see absolutely no reason why this shouldn't be possible, even probable. The price of a gun does not determing its handling characteristics any more than it determines its stock dimensions. It is the relationship between the shooter and the gun that makes magic, not the shooter or the gun alone.

So, what do we get for our money in a gun? $3,000 - $5,000 buys about all the longevity and reliability most shooters need. From there, you buy fit to your dimensions, handling to your desire, coverage/quality/uniqueness of engraving, wood quality/color/figure/finish/carving/checkering, metal finishing, fit of parts, and name. The truer you are on your specs, the more likely that you will wind up with a magic gun. Keep in mind that the gun will not be magic for most other people; they have to find their own.
