I was out at the club today, and after my rounds was engaging in some informal dumpster diving. I found tons of black Remington 12 ga. hulls. They are marked High Velocity. Curious, I cut one open, pleased to find that it was a one piece hull. I cannot find any reference to this hull in my reloading books. Can I use the Nitro/STS data since it appears to have the same internal dimensions? (that would be nice!)
