There are various ways to ignore the handgun ban. LBRs and LBPs, as mentioned. There are a few designs out now, and it seems we get 2 more each year. Alan Westlake (also the chairman of SAGBNI) makes 2; one a cut-down Browning Buckmark .22LR semi-auto rifle (£500), the other a long-barrelled Britarms pistol (.22LR semi) (£1000). There is a .22LR revolver in this month's (or is it last month's) Target Sports. Think it's a bit cheaper than most. Taurus has a line of LBRs, but they aren't cheap (£600), they are in a number of calibres. And Southern Gun Company does some single-shot long-range pistols in a variety of calibres but I don't remember the price. Oh, and there is the Uberti Buntline... a Colt SAA clone/reproduction with an enormously long barrel.
