Just got this responce from Mike Remo at Anzioshop.

"Hi Frank,

Thanks for the heads up. All the 20mm ammo has been loaded with the early style percussion primers. The weapon has a traditional firing pin arrangement and interchanges with 14.5mm Russian, converted vulcan 20mm or the 20x110mm hispano round. We only sell the electric primed versions to government agencies for testing purposes.

Thanks again,
Mike"

Ok, so you'll be fine so long as you use the ammo from them, but what ever you do, if you ever get one of these, don't go getting ammo from the military. Two different types of ammo. Be sure you use CONVERTED AMMO ONLY.

Got to admit though, that'd be one hell of a squirrel gun. :mrgreen:
