RE: shogun slugs out of a mossberg 12 ga
I shoot Brenekes out of my Mossberg 500 12. This would depend on what best shoots out of your barell though. I have an original mossberg 500 rifled, ported slug barell on my Mossberg. Not a Hastings or other mfgd barell. It has fiberoptic sights as well. If youre running smooth bore I recomend the ferderal 3 Inch mag sabot,if you can handle them.
