I would be stunned if any significant improvements come in the next few years. Maybe, if we're awfully lucky, by the time y'all are ready for a new rifle anyway. But for proven concepts, likely not for two or three cycles of new rifle building. How many of you are still shooting rifles built before 1995?
It's no doubt premature to bring it up, but there was a post on unlimited where I asked Jerry Hensler if something would work, and his response was, no, it takes mass. Now this was about rail guns, and whether a (say) 30 pound could do what a (say) 70 pounder could do. The subject was controlling barrel movement, as I recall.
Mass can hide a lot of things. To say there is an experimental class, unlimited, overlooks that.
It's one thing to experiment. It is quite another if the eventual rifle won't be legal in competition. "To hell with it, I won't even try" is an appropriate reaction.
I see the move in sporter as a positive way to lean something. And if that's not on the agenda, why not stick with muzzleloaders? Cheaper, if you'll dump the time limit...
