Thanks Dale.R.W.Dale said:Regardless of rim configuration bottleneck = case setback
I think I can grasp what is being said here, but after a little research, I think I've become even more confused. The image below shows an factory, unmolested 5.7x28 cartridge on the right, and a mystery .224 revolver cartridge on the left. What's intriguing here, is that the rimmed cartridge shown, apparently doesn't have the setback problems alleged here (at least it hasn't been mention in any reviews I've read). Otherwise, they probably wouldn't be selling a revolver chambered for this round in the first place.
* Both shown are 'necked' cases.
* Both are straight-wall cases.
* Both share almost identical ballistics.
* Both are .224".
So why one and not the other?
