The most important habit anyone should develop, IMO, is that of either firing both barrels before reloading, or pulling the cap off the nipple on the still loaded barrel before reloading the other....................if you value your eyes and digits. Firing both barrels is by far the safest of the two.
Jon, I'll try to remember to take a pic or two of my loading setup for doves. I came up with the ideas after my first dove shoot with a m/l some 30 years ago. You'd particularly like the loading rod holder, I think.
