RE: mossberg 500A is it a deer gun?????
We are not saying you can't, just that it doesn't work very well and is not worth the extra money sabots cost. You can get good rifled slugs for a couple of bucks a box, sabots will run you around 10 bucks and up. And don't even bother with the newer high tech faster stuff, I doubt it will shoot worth a darn out of a smooth bore.
Try some brenike's if you can find them. I hear great things about them. I used winchester rilfed slugs out of mine, worked fine.
I traded the mossberg in on a H&R slug gun though, works much better.
