I have not killed anything other than paper targets with my Mossberg 500A
with a 20" ic barrel as it is mostly for home protection & my best choice for
it has been 3" mag #4 buckshot & 12 ga 1oz slugs. I have had some fun with
it firing #6 game loads on clays & it is what I have been carrying when I have
filled my big game tag as Pop tries to fill his! I "tricked mine out" with a pistol
grip & a pistol grip foreend & a top folding stock with a 6 round side saddle
ammo carrier. Thanks to "Tac-Star"! (When it sits in my gunrack... I have
even got a "thumbs-up" from many leo's)!
