I have a mossberg m590a1 was just wondering what effective range a slug has out of the 18.5 in barrel?
We are talking about Brenneke/Foster type slugs. They are all designed for smoothbore, the sabot slugs and plumbata slugs are designed for the rifled bore guns.If memory serves the 590a1 has a cylinder bore smooth non rifled barrell. With smooth barells 75 yards is about the farthest i would shoot. Remember a lot of slugs out now are for rifled barrells and they won't shoot worth a darn in a smooth bore
