Hi Pilgrim South,

As was earlier mentioned a youth model Remington 870 Express chambered for 20 gauge (Wal Mart has them inexpensively) or a youth model Mossberg 20 gauge pump would probably be the least expensive way to start. (If you think you may be serious about sticking with clays, start with some type of repeater, not a single-shot.) But recoil will be a little more stout than with a semi-auto.

For a little more money a 20 gauge semi will help with recoil reduction. I have no experience with the Charles Daly line as sold by Wal Mart, but you might be able to get a youth model Charles Daly 20 gauge auto for close to the price range you're looking at. A Remington youth model 1100 semi-auto in 20 gauge will certainly cost more...but would last you for a lifetime of shooting!

A decent double will cost more yet!

Good luck with your search.

Dave
