I have a Rem. 870 with the fully rifled barrel and Bushnell scope. I have been sighting it in with the Lightfield Hybred EXP sabot slugs. These are the 2-3/4"shells with a 1-1/4 oz slug. They shot pretty good at 30 and 50 yards, but seem to drop off alot between 75 and 100 yards. I have them pretty much zero'd at 50 yards. They seem to be dropping about 4-6" at 85 yards.(distance by rangefinder)

What does everyone else experience while shooting them?
