RE: shot gun slugs
My sons and I used slugs in PA, VA, and IL. We had five shotguns some smooth and some with rifled barrels and we went through a lot of what has been discussed. We had three 870's and two 1300's. During testing i was never satisfied with the sabots having a significant advantage over the regular Winchester and Remington slugs. I ended up going through two additional barrels for the 870's and one for the 1300's. The goal was to get four good shooting guns. Strange as it seems we ended up using the regular slugsfrom Remington for the 870's and Winchester slugs for the 1300's. There were some sabots that shot a little better but not significantly.
Where we hunted most shots are within 50 yards. We have been successful at shooting deer out to 75 yards with these guns.
