Hi guys, I got the 3" .410 to .22 LR adapters in the mail and got to shoot them after church today. I got the steel unrifled ones and shot them at a distance of a long 12 yards, 36+ feet. I used Federal American Eagle Hi-Speed HP .22 LR shells and a H&R single shot .410. The fit and finish of the adapters was very nice and if the empties did not shake out they could be easily bumped out on the wooden shooting bench. There MAY be enough to put a thin piece of tape on the forward end of the adaptor for a snugger fit but I don't see the need, besides, whatever you put there would have to very, VERY thin to fit.
I got a consistant 3.5 to 4" max groups of 5 shots each from the adapters, even though I do not think all the rounds stabilized. Good enough for a coyote head shot at that distance and to dispatch other small game. I indexed the .22 LR chamber at the very bottom of the shotgun chamber for each shot. Interestingly, each of the adapters grouped it's shots directly on top of where I placed the bead on the target, very consistant.
These adapters could also be used very well with .22 LR (bird)shot cartridges for small vermin up close or with a solid bullet to dispatch a wounded or injured anilmal w/o having to use another shotgun shell.
In a camping or survival situation you could easily carry the adaptor and a couple of boxes of .22 LR or .22 Short shells either in a storearm forearm, Survivor buttstock, or a pack. That would give you plenty of extra shots if needed.
All in all I am pleased with them, not for long range target work but accurate enough so I will be keeping several for myself, at least one for each grandchild. I will use the adapters to start them with .22 (bird)shot cartridges in a .410, easy to hit with, no recoil, hardly any noise, and lots of fun and reinforcement when they hit a lot of easy targets, ballons and such.
And by the way, yesterday my son and daughter-in-law pleasently surprised us with the great news that we are expecting another grandchild.
HAPPY DAYS!!!....<><....
P.S. - I think I am going to try .22 shorts next, both standard velocity and high speed. They should work just as well as a .22 LR and would take up less space and weigh a bit less as well...
