Well, that is correct. It is SB2. I guess that's my question. We're back to pistol loads in a carbine. If you look up "rifle", It'll show you rifle. If you look up handgun, It'll show you that. There is not one on line source that I know of that can give you rifle and pistol ballistic information for the same load. Totally stupid on the manufacturers part. Ya wanna sell bullets and components, do some homework. Get yer butts in gear and give us some pistol caliber load information.
