what ???????????????the 410 is a caliber, not a gauge. It works out to about 67 gauge, though oft one hears it referred to as a 32 gauge.
I want to see some pictures !!!!!thank you re for the .32 link! My H&R single gun is going to fire Fiocchi soon. Should be fun. Bpi has slugs to load for it plus data. Did you guys know Win 86's were made as speial orders in .32 gauge? From Cartridges of the world. I never heard of this gun before. Thanks all for your input. Have fun and bangaway.
and the .32 guage would throw well over a pound of lead per shell.
