I prefer the DG Slug. I shoot them out of my 12 ga, and my kids shoot them out of their 20 ga. I have tried many slugs, to include some of the most expensive slugs, and have gotten the best results with the DG Slug roll crimped. All the barrels are Remington rifled, with open sights. They are extremely easy to load, economical, and very accurate out past 100 yards. I use 3" for the 12ga., and 2-3/4" multi-hulls for the 20ga.
These are for smooth, and rifled barrels, but I have only used them in rifled barrels. They are very effective on deer.
