Yeah - I'd rather not. They don't drop when on fire, they still run/amble around, setting shit on fire you might not want set on fire.
They would be fine against zombies. The one fellow's dismissal of .22lr for anything but "whites of the eyes" range is unfounded. Yes, a .22lr can do weird things and bounce off of a skull, or I've seen a case where it zipped along between the scalp and the skull. But these aren't your normal occurrences. Could it happen? Sure, but how often? 1 out of 100? Even giving it a generous 1 out of 4 chance, you just follow up with a second shot, it doesn't negate all of the other benefits.
At 100 yards and a medium sized even a novice could hit head sized targets all day long. Set on a bench, you can get quarter sized groups or better. 50 yards with a red dot sight.
While it is kind of silly to label a 10/22 a tactical (hey, it helps sell stuff), I picked that variant for several reasons. The stock is thick and sturdy, and unlike wood, it won't warp if wet and won't splinter if used as a club. It already has a rail installed to mount a scope or red dot sight. The bull barrel is thicker for more accuracy and less likely to bend if used as a club. The bipod might be a little superfluous in some cases, and just what is needed in others.
There is one other version they set out to make which is very similar to the one above, but the barrel is already threaded for a suppressor.
