Nasty "Black Rifle" baby eaters with 3 evil features would make a wonderful ergonomic hunting rifle. Alas they are restricted in Canada and can not be used for hunting. The 3 evil features are not relevant in Canada but they get California's panties in a twist. Gun laws are perverse in all their glorious forms although the Brits in their infinite wisdom were responsible for unwittingly creating a massive multi party endeavour to thwart one of the earliest gun laws we know, thus giving the world all manner of lovely Nitro Express cartridges to choose from!

Anyhow, could one drive a heavy bullet in a super short case fast enough to make it practical for short range hunting for light big game? I have experience with a Ruger Deerfield in .44mag that will shoot 240 grain bullets well out to 50 yards but sighted at 50, the bullets splash the ground easily 30 feet short of and ten feet below the 100 yard targets.

I think of those sexy long Nitro Express cases that eat 100 grains of powder to get a 500 grain bullet going at 2100 FPS and I think of the much shorter .44 mag case that launches a bullet half that weight at 200 FPS slower and it makes me wonder about the efficacy of this adventure.

In any event, I am unfamiliar with these short big bore cartridges that you are looking at. Is it fair to assume that they are intended to have similar bullet weights and velocities to the .44 mag?
