In the FAQ section of the XCR company web site, it says "It will handle .308, .243, 7mm 08 and other calibers based on the .308 case." I understand that if the case diameter of the different calibers is the same, then they would fit in the same chamber.
But, there are two things I do not understand about how all the other calibers can work in the .308 rifle.
First, doesn't the length of the cartridge make a difference?
Second, what about the diameter of the bullet? Wouldn't, for example, the size of a .243 bullet be too small for the barrel?
Thanks.
