indeed the 10 guage does exsist and so does an 8 guage. the order from big to small goes 8,10,12,16,20,28,410,9mm,.22 cal the 9mm and .22 are actual bullets with no lead. there is a glass shell filled with #9 shot where the bullet fits into the brass. they are not used for anything more then killing snakes or rats. also the 8 gauge is no longer in production the only ones you will find are very very old black powder long guns. which are muzzle loaders. probably not safe for firing. the 10 ga. is still fairly common but will soon go out of production also i presume. the cost for one shell is over 1 dollar. a box of 25 is about 40 dollars. very expensive and impractical. do a little research on the 10 ga. look it up on gunbroker.com and then look at the shells. also type in 8 guage shotgun and you will have a page or so of antiques. if you have any questions just p.m me. thanks
