If you read the advertisements from all of these new products, they all say, "improving the flaws built into the conventional action based on 100 year old designs".
This is typical when pushing a product, especially in a field that is saturated with a myriad of different designs based on the same concept.
Just because something is more complex, has more parts, and contains ideas that, on paper, promise to insure a better product, does not nessessarilly mean that it will offer better performance.
That "performance", in the game of Short Range Benchrest, translates to shooting winning Aggs, or Scores, in the Competitive Arena.
I don't know how many actions I have owned in the past 20 years. I've seen just about every "new innovation" come, and many go. Many, as it turned out, did contain very unique solutions to "problems" that simply did not exist. Or, to be exact, do not exist in the real world.
Much of this is due to that now not so recent advent of CAD/CAM machining innovations, which allows just about anybody to design, and manufacture, anything that the mind can dream up.
We will see.
But when you sit down with your new latest and greatest piece of machinery, and some guy with a 30 year old Panda and a GREAT lot of bullets takes home the prize..........well, think about it.
