Red, your gonna be pissed at me but I find that people that lack knowalge buy into hype

. If anyone makes the statement that a short case is more effient (gets more velocity with less powder at the same pressure) they have not done thier internal ballistic homework. Potentental velocity of a cartrige is detiermined by case capacity not case shape. This can be backed up mathematicly. Velocity rises at 1/4 the rate of case capacity.
The thing with the short mags is that there is no real "incremental change" that is to say, there has been no new technology layed down. We have not been able to break any balistic rules with the short mags. Even the case shape is nothing new, people were wild cating when I was still on the boobie.
All and all it comes down to the fact that the new rounds are a variation on exisitng knowlage and technology. There is nothing new here.
The act of selling a new cartrige based on hype and out right lies is why many people bash the short mags.
I gotta go now so I can bash the new "smootest feeding magnum ever invented"
