The 220 Swift and the 22-250 pushing the same bullet (and I meen the EXACTLY same bullet will have the exact same ballistic co-efficient. The only way for the BC to be different is to use two (2) different bullet designs.

If these bullets are the same (i.e., same dia. weight, length & design) (an example would be two 55 grn ballistic tip bullets for that caliber) then the BC will be exactly the same.

If for example you are comparing a Nosler Ballistic Tip bullet with a Sierra BTHP Match then the BC will be different.

My last words on the matter.

Winchester 220 swift 40 grain BST: BC: .221

Winchester 22-250 Remington 40 grain BST: BC: .214

Sorry, but they are different. If you handloaded with the same bullets, or bought from certain manufacturers(Hornady I believe does this), that's a different story.
