So I went out to the range today to sight in my new rifled slug barrel and scope on an 870 express, and after shooting two types of Remingtons, Winchester, and Hornadys, I'm still not able to get the accurate groupings at 50 yards (the max distance for my area). The Remingtons both did well at first, but then got a couple fliers from each type, the Winchesters gave me at best a 6" grouping, and the Hornadys also gave me a good groupings at first, but had a couple fliers as well. So, after spending over a 100 bucks on ammo, and with a very bruised shoulder, I'm a little fumed. A friend suggested trying rifled slugs in my rifled barrel (he does with his), as they're much cheaper, and according to him, more accurate. Any suggestions, or should I just buy a rifle like I first thought?
