As I look around the internet for more information on these Model 340s, I note that there are different removeable mag.s for .222 and .223. Are these cartridges different enough that .222 magazines could not be used for .223?
(I'm starting to think I would be just as happy to use a 340 in .222 after all. But I don't see a pelntiful supply of cheap, bulk-packed varmint ammo for .222 like is available for .223 from Black Hills, etc.)
