The other day, someone had a thread about a 8mm rifle. Having never heard of such, I googled up a conversion site and looked it up. Then as a fluke, I checked some others that I thought I knew. Such as 6mm = .244, nope = .236...... What about 6.8 = .277, wrong again = .268. One more try, 5.56 = .223, nada = .219
My reloading stuff is all boxed up, while I'm remodeling a house, so I cant go grab a bullet and check it out with the calipers. So what am I missing?
