I am not, and never ahve been into shotguns very much. About all I know is I use #6 shot to hit a rabbit on the ru, as I could never hit him running with a .22. Yes, I have a few, and I shoot them, ocassionaly. But I have a question, I came across this beautiful Marlin 12ga bolt action at a LGS. Like new , beautiful wood , with beautiful checkering, but... It has a rifled barrel. The guy said it is great for certain type slugs , accurate at 100 yards. Is it? Certain type? Now ....how does that rifling affect shot shell pellets? I can also shoot slugs with my smooth bore guns. If this thing can throw a huge slug accurately at 100 yds, then I might be interested, Because my 45-70 Govt rifle throws a fairly big piece of lead accurate at 100yds, and cost 3-4 times as much as that shotgun. Anybody help me out ? Jim btw, I think its a Marlin 512 Slugmaster.
