Anyone here tried the .19 Calhoon, the .19-.223 or the .19 Badger? I met a guy last week that converted a XP-100 into a rifle in the .19 Badger. He said that is was tremendously accurate to 300 yards.

I have an XP-100 that should be turned into a nice rifle I think. What do you folks know about these Calhoon rounds?
