There were lots of .222 over 20 gauge, and a bunch of 22lr over .410. I have a 30-30 over 20 gauge and the later ones ?? over the 12 gauge. I think in rifle cals there were only 22lr, .222 and 30-30, could have been a .223 in the later modles. Mine is my most used rifle, it doesn't do anything best, but it does most everything. Larry
