From old information, I can confirm that you fellows have intuitively focused on the problem. But I can't give you specifics on dimensions. I've been looking for those for a number of years.
I remember reading a discourse by a shooter who was going through one of the high-dollar schools in England, either Holland or Purdey, and when he complained of the same problem, the master gunfitter told him immediately that the problem was improper gun fit. He alluded, however to the fact that it was more than simply angle of the hand of the stock.
The English actually have a number for what is supposed to be the acceptable minimal distance between triggers. I had it one time and didn't write it down and I've been looking for it ever since.
Going to a pistol grip is supposed to largely cure the problem. But that is certainly not true one hundred percent of the time. Some guns like the old Remington 1894 have a poorly designed trigger guard without enough tuck up and under. They are known as knuckle busters. I had one with a half-hand and there was nothing that could be done to keep it from hitting my finger.
I personally feel that having too little room on top of the hand of the stock is a major part of the problem. If you actually have enough room between the safety and the onset of the comb to get the web of your hand over the top of the stock it will largely eliminate the bite. Most stocks are not made that way but it is a very comfortable feel.
