I replied to your GD post, but again, I would make serious contact (do NOT just speak with a secretary , etc. insist on speaking directly to the head of sales, etc.) with several companies...especially Beretta and Remington, and tell them what you are doing, then ask if they might see their way clear to assist "in any way". My guess is that someone, somewhere will see the advantage in starting college kids off with a XYZ brand claybuster special...GREAT long term marketing potential, and a tax write off as well! You will definitelt need serious documentation and maybe even a college dean, etc. to sign off on this, but I think you can get a gun or two for a VERY nicely discounted price. Both use email for most contacts...

If that avenue fails, try as many major distributors as possible of the guns you are interested in. Sales guiys sell demo guns all the time at the end of a model year...maybe you can get one or two at a good price.

I have zero knowledge about the CZ shotguns except that they are not built by CZ...they are likely a decent shotgun for what you need.

Good Luck
