Those articles are by Warren Potter, a coach writing about pistol shooting (but I don't see why most of the trigger advice wouldn't apply to rifles.) Gary Anderson and many of the other greats lectured the Juniors at an Olympics team trials in the '70's and the lectures were transcribed and sold in two volumns as "Schiessport Schull" I and II. They were expensive, available only by mail and I don't know if they're still available but I'll find out. I'll gladly snail mail selected excerpts to anyone interested. There are talks by Jack Writer, Lanny Bassham, Margaret Murdock, Lones Wigger, Bill Pullum, Dave Kimes and others. Great historical document for a fan and more than a few tidbits for shooters. I think it's Anderson who stresses that thinking about follow-through BEFORE the shot breaks helps him to break it cleanly.
There's an interesting follow-through drill in "Ways of the Rifle," probably the best technical shooting book around. It involves removing the rear iris of an aperture sight, letting the target blur, and just watching the front aperture rise and fall in recoil (and then plotting each shot, the muzzle movement, not the hit. We don't care where these shots hit.) Bet we could do this with the dot and use the cheap ammo, too! It's hard just to learn to watch it and even harder to make the muzzle rise straight up and fall straight back in the same pattern...a very grueling exercise according to the book.
"Man, folks," (as Bill Calfee would say) I bet if we did enough of these very simple exercises, balance exercises, little dryfiring and what not, we'd "...find points coming thick and fast."
