Back in October posted about having trouble sighting a Rem 1100 cant riffled barrel. Tried just about all brands of sabots. Best that it would produce was a 6" to 8" zero. Switched scope but that didn't help. Noted that the syn forearm was extremely tight. Using a Dremel, reworked the forearm so that it was basically free floating. Went back to the range last week and shot a 1 1/4" group with Remington Accu Tip. Problem corrected.
