OK...I'm guessing this forum will be the best place to ask this. My wife (bless her little heart) went garage saling today and picked up some stuff for me.

One item is an old H&R 410. Its barrel is marked "410-44 CAL"......what the heck does that mean? I'm guessing it is a short 410 shell but I am shotgun ignorant......
HELP!!!!!
