What do you guys think of the short lane 12 gauge shotgun chamber adapters? They seem like nifty little gadgets for a break open shotgun. Thinking about getting one in .38 Special and maybe another in .22 or .22 magnum. Any eperience with them in those calibers? I'm not expecting extreme accuracy of any kind. Would they work safely in my old Winchester Model 37 "red letter" break action single shot 12 Gauge?
