Re: question on reloading .223....... .224 bullets?
Yeah, all true. There is the 225Winchester, the 224Weatherby, the 222Remington and the 220Swift and they all use .224" bullets. There are a few older Hornet rifles that actually use .223" bullets to further confuse the novice. The 243Winchester uses 6mm bullets, (.244") just like every other 24 caliber rifle.
Once you understand that there are standard bore sizes and <span style="text-decoration: underline">many</span> different cartridge designations, you can forget the confusing numbers....in most cases. Whatever happened to 21 and 29 caliber, I wonder?
