Sometimes the wheel needs to be reinvented . . . or memories refreshed. It's like a number of the "Finding Out For Myself" series of articles Sherman Bell has done in Double Gun Journal. Much of what he covers (like using shells the fired length of which is longer than the chamber in which they were fired) was covered by people like Burrard and Thomas in British publications, but not necessarily well-known on this side of the pond. Refresher courses (or reminders of previous discussions) can be valuable.
