[That and the weight of bullets for the 223 are limited to the rather lighter weight bullets as where the 250 or 220 shoot heavier bullets as a whole for better wind bucking results./QUOTE] beings how the 22-250, the .220 swift and the .223 are all 22 calibers, I've got to ask: do you not realize any bullet than can be shot through a 22-250 or swift can also be shot through a .223?
While that is technically true the 22-250 and 220 Swift have faster twist rates generally that allow them to shoot the heavier bullets more accurately than the .223. You can get different barrels with faster twists that allow you to shoot .223's with heavier bullets accurately, however. 1 in 12 twist are good for small bullets at high velocity. 1 in 9 twist is good for heavier bullets. You can shoot the heavier bullets out of the .223 but you will suffer in accuracy and will burn your barrel our quicker. The bullet size just depends on the gun and the twist rate that you purchase.
