Although less efficient than a sliding comp tube rifle, and potentially not as accurate, one absolutely wonderful thing about those tap loaders is the ease and safety.
Once, at one of the Bashes, I had a go with various tap loaders. And the speed and ease of loading was great. From a safety point of view, brilliant.....for the first few shots, having been conditioned to safe handling practices with break barrels and slidy guns, I was holding the under (or side) lever.
Once re-conditioned though, it was great.....cock gun, return lever, flick the tap, drop a pellet in, close tap and shoot. Takes far longer to describe than to do.
And the one that I simply MUST have is one of the Lincoln Jeffries / BSA pre-war underlevers. I've loved every single one that I've tried.
One day, one day........
