I'm sure it was discussed before. And I wasn't sure if it should go under Rifles or Shotguns section so I'm posting here. I was thinking about casual hunting. You don't know what you going to be hunting, maybe rabbit or squirrel or maybe bird. Shotgun might work for all, but sometimes it better to take longer distance shot with 22. Can't really carry 2 rifles. I saw a combo O/U on sale at Armslist and got interested. Who made those? Did those 2-in-ones get any popularity? If so, which makes/models? Basically any info about those appreciated.
