Fred Kimble “The price of good shotgunnery is constant practice.”
More wise words from Will K. Park, Editor,
Sporting LifeAs the drowning man clings to a straw, so does the shooter love to think that his load or gun may, instead of himself, be responsible for a referee’s “lost.”
BTW: turn-of-the-century Live Bird shooters frequently used some form of the low gun "ready" position before calling for the bird. E.D. Fulford in 1897

Brief live-action shooting at the 1912 Stockholm Olympics is here; some essentially pre-mount, others low gun "ready" position.
https://www.youtube.com/watch?feature=pl...t-ts=1422579428 Olympic rules called for "gun below the elbow" set-up.
Ed Banks' comments thereupon:
"The conditions of the Olympic competitions at Stockholm are, in the main, those usually adopted in England, there being 15 traps to the five marks, but a point which is of considerable importance, and will need careful attention by the competitors of all nations, is that the “gun below the elbow” position is insisted upon.
Game shooters, on first taking up clay bird shooting, invariably decry the “gun at the shoulder” position. If they continue to take part in competitions they end by adopting it, because there is no doubt at all about its advantage when conditions are “known traps” and what might be called the “flushing point” of the bird can be covered."
