Ammo is available from J&G Sales. As to whether you can shoot standard ammo-see the thread "9.3x72R?....." in the German and Austrian Guns Forum.Especially read Axel's comments.For whatever it's worth, I have been using drillings 50+ years and much prefer 16ga with 60-65 cm barrels in any of the 57mm long calibers. 9.3x74 and 7&8x65R as well as 8&8sx60R are great. 9.3x72R, 8x57R/360,8x58R are acceptable, but 6.5x58R,5.6x52R,etc- I would want in a second or third drilling-not the main one.If you intend to hunt with it, a scope is very important, a 22/22mag insert barrel is useful but not necessary. Be sure to either inspect it before buying it or get the right to return it within a reasonable period.Check very carefully for loose comming ribs and badly fitting stock(oil soaked/rotten).30-06 is a wonderful caliber, but I absolutely do not want it in a drilling,or any other rimless cartridge for that matter.
