Twelve gauge gun like that with 70mm chambers is very practical choice. Both lead and steel 1oz loads can be found for <$6 at Walmart 24/7 smirk unless one lives near economically-challenged hood there ammo sales stop at 10:00pm. blush The light steel shot 6 and 7 loads should be ok in barrel choked 1/2 or less. One must remember that in the future ammo delivered to door may not be allowed. cry
Sadly anything is possible. After 227 years of liberal gun ownership policies (good stuff like CC w/o a permit) it now appears the State of Vermont will have magazine capacity limit, universal background checks, waiting period and minimum age to purchase firearms. All it took was a Democratically-controlled legislature and a Republican governor afraid of student activists. cry
