I remember one account of Bell written by whom I cant remember, told of his self taught shooting technique. Bell apparently taught himself to use a Bolt Action. Now instead of keeping the but in his shoulder he would pull the stock/rifle forward while working the bolt rearward and then bringing both back together. Worked for him and may explain the odd poor shoot placement.

Same account also told that when Bell was shown the 308 he thought that might be the perfect calibre for Africa. Maybe for him, not me, I am not that cool or good a shot.
