Same old Wonk. LOP doesn't make a bit of difference . . . nope, doesn't make much difference when you're shooting nothing but targets, pre-mounted. No more than gun weight matters, when you're only toting the gun from the trunk of the Mercedes to the 16 yard line.
If one accepts the late Gough Thomas as a "published authority" on shotguns, here's what he says: "Since our leading coaches and gun-fitters cannot always agree on what constitutes the correct stock for a given man, I beg to be acquitted of any intention of laying down the law on the subject." It would seem that Mr. Batha, who is a coach, has as much right to submit his opinion on the subject as anyone else--given the lack of agreement to which Mr. Thomas refers.
Same old L.Brown. Never bother to read an entire post if that will interfere with a reply that has no bearing to the topic. You might want to obsess about something that you actually understand. And I am absolutely certain that Gough Thomas would be the FINAL authority in gun fit since his international shooting fame has no equal. I know that my meager experience is of no consequence but the "authorities" (i.e. successful shooters) that I have spoken with seem to agree on the drop/cast/pitch/lop thing pretty consistently.
And I don't mind saying it again - gauge has as much to do with drop as my shoe size. Just like cowboy boots will make your gun shoot higher. Well, maybe at the urinal.
And I would end with JMO again too, but obviously there are facts that need no substantiation by my opinion or experience; the drop/cast/pitch/lop interactions being the most obvious here.
over and out

PS - Yardley does the writing/shooting thing for a living. Buy his books. He speaks the truth. And go to shotgunreport.com for a DIY gunfitting tutorial that works. AND just BTW for L.Brown, the shotgunreport guys are killer international and sporting shooters. But WTF do they know anyway??
