Have any of you ever heard of "Sabotted" ammunition being offered in calibers of than .308? Also, shouldn't any .22 caliber bullet be able to be loaded using standard sabot technology in any .308 caliber rifle? For example, shouldn't it be fairly simple to load a 7.82 MM Warbird with a .22 caliber - 20 grain bullet and launch it out of a 30 inch barrel? Even a .22 caliber - 80 grain bullet should come out pretty fast and if it's a VLD bullet with a Ballistic Coefficient of .489, it should be pretty flat shooting. A 7.82 MM Warbird should be able to kick out a 80 grain "Accelerator load at over 4,000 fps I would think. Could you imagine launching a .22 caliber - 20 grain bullet out of a .50 BMG without having to worry about the extremely short barrel life and potential for explosions you would experience if you necked the cartridge down to .22 caliber?
