We all have our views on firearms I am no different I like bolt rifles, revolvers and shotguns. I have ammo for all but not thousands of rounds (except 22). Sometimes when your out hunting seasons over lap carrying multiple guns into the woods is not an option.
We have all heard the saying "Eat lead". In the movies it usually means getting shot but it is a term that is way older for game that is riddled with shot when cooked and eaten. Side note in England it is bad manners to remove anything from ones mouth at a meal unless it is "shot" from wild game. Ever shot a squirrel with a 12 ga. doesn't leave much to eat. I have been looking at getting a set of these Short lane adaptor's . I have guns that take these shells already but I don't always have them in the woods.
This 70$ kit allows me to choose 5 different calibers when hunting with my double barrel 12 Ga. YES I Know they aren't as accurate as A Real Gun but everything has trade offs. It also makes one gun capable of digesting all the calibers I keep on hand if I order just 2 more in 38 and 9mm (these I want in rifled 5").
While I could use them in the double barrel it was my grandfathers so I would prefer a newish single shot for this platform. Even brand new for all I would be under 300$ with 7 calibers possible including gun. No it will not be a Tack Drive but it can be useful. If ammunition disappears again or gun laws change this platform will be able to handle what is left.
Not even the DEMwitts consider a single shot 12ga a threat.
