Dick;
Ya'll will have to do a little searching, but I'll get you pointed in the right direction. If you google "black powder shotgunning" you will undoubtedly find the Seyfried article...and a good one it is. Also, if you do a similar search for the winchester 76 you will have to sift through a few articles, but you will no doubt find the one that lists the different things Winchester did to prove the toggle link action was far stonger than people gave it credit for.
I wish I could post links, but these searches were some time back, though I read the articles this year so they should still be available.
