I don't know why we go on like this except for responsibility to answer questions from less experienced members about the safety of using shells of a particular length in particular guns.

My guess is 99 per cent of members use/used shells of longer length in chambers, know the characteristics of nitro and blackpowder, and do not know a person who lost fingers or worse.

This isn't to down-rate caution and safe practises. Surely the board can provide a canned, short answer so the less experienced aren't burdened by well-intentioned information they don't need.
