My dad had a 10ga - it was a old h&r 176 single shot mag -Ive shot it twice in my lifetime - once when I was 7 had to pick myself up after but didnt drop the gun and once about 2mos before we lost him - had a 3 1/2 mag in it both times - have to say I dont have the want to shoot that thing again - I can only imagine a dbl barrel - have fun LT6
