check the EE, theres tons of single shot shotguns floating around. personally, he handiest single shot i ever had was a baikal take down 12 gauge i had in high school. the barrel had been professionally shortend to 18 1/2'' by a local gun smith.
i called it my 'hooky gun'. I used to get ready in the morning, hid my school books and put a hunting vest, the gun broken down, some shells and a lunch in my bag. id leave the house 'to catch the school bus' and keep walking up the road. id hunt partridge all day, hide them in the woods and go home to meet the bus.
once i was home, id go downstairs, assemble the gun, put on my hunting clothes and say the i was gonna go try to shoot a partridge before supper. usually id be gone an hour and come home with 6

they thought i was the best partridge hunter on the north shore
