iwantadouble , there are no sutpid questions where firearms are concerened, especially double rifles! I don't think you could think of anything that has not been tried to make double rifles esier to build, and make shoot properly. That being said, the opposing twist theory has been tested many times, by many makers, without any thing being gained. It simply doesn't matter!

The group you posted would gender a lot of load testing in my digs. I'm sure your rifle was regulated far more tightly than that, so the load you are useing is not right, by some distance. If it satisfies you, however, it is your rifle. Since you are not hunting with this rifle nothing is lost if paper is punched in a wide group, as paper doesn't suffer! Addtionally, you will not get a horn up the butt if you fail to stop something that wants to hurt you!

Your comment about the kill zone being much larger on an elephant, or Buffalo, than the group you posted is a fair statement! The actual kill zone on almost any animal is larger than that group, however the stopping zone is much smaller than that group in many cases! your group statement could be hazardous to a young guy who may take your meaning to be that that group is good enough to hunt those animals. It is NOT! Though all your shots may be in the kill zone, if none are in the stop zone in a close encounter, it may result in a very flat, and tattered hunter, before the kill zone shots take effect!
