I agree with Dave McC; I have tested probably every brand of slugs made to date, including some reloaded ones. Sometimes it is hard to believe the differences the way one gun will shoot a particular brand and another. The most accurate slug gun I have is a Ithaca Deerslayer ll as it shoots most slug into small groups, but there are brands it just won't shoot well. Try a bunch of different manufacturers and see which YOUR gun shoots well. Incidently, I have had the best luck with Remington Copper solids, Hornady slugs and Lightfields. At least in my guns.
