Try using a service issue M6 by Ithaca in Alaska without extractors while wearing arctic mittens. The only real alternatives are the Savage combination rifle, or the even heavier Valmet and Baikal units, usually in 7x57/ .308 over a 12. The successors to Harrington and Richardson have offered the basic singlebarrel shotgun with interchangeable .22 Hornet or .30-30 barrels. Just try to find one.
