Yes you can shoot 410 shells in your 444!
I have only fired the 2 1/2 inch in mine, haven't tried the 3 in.
They will fire and they will extract!
They would be very effective on the "fool hens", I know you can sometimes get pretty close!
The case will swell considerably more in the 444 chamber than it would in a 410 chamber, so, in my opinion, they're throw-away's!
As stated by Mikey, they won't work through the action! Single shot only!
Whenever I use my 444 for deer hunting, I usually carry a few 410 shells!
I know they are good to 10-15 yards on grouse! That's the farthest I've shot!
