Thanks, wburns, for the rationale behind it. I do not agree with Mr. Churchill, however. When the hand is repositioned ever so slightly, after taking the first shot, the leverage should be very nearly the same. I have never noticed any difference in leverage, but I DO notice a hard, or creepy, trigger. I am fussy over my triggers, not tolerating what I consider a bad one on my guns.
I shot the NWTF Sporting Clays Shoot this past weekend, and in the S x S event I was talking with a fellow competitor who was shooting a M21, and rather poorly. He blamed a lot of it on his rear trigger, which he said was something approaching 10 lbs. He is a seasoned S x S shooter, who used to compete with a Purdey. Though I did not, I wanted to ask him why in the world he even brought such a useless thing to shoot. I'd much rather shoot a 311 with fine triggers than hi-bred queen with poor ones. Anything that takes the shooter's attention away from the bird in flight is to be avoided, IMO.
