I have it down to just 6!
You have my deepest and heart-felt sympathy.
Why? the only two I could use in Ohio was 20g or .22lr, everything else was bow and arrow!
My apologies to the OP!
There are some impressive lists here.
Those listing all three of the 22’s, short, Long, and Long rifle. You actually have a gun in all three chambering.? Even more impressive.
