Hi all, I have a nice 16 gauge Merkel drilling and am considering using the Brenneke 2.5 inch slugs in one or both barrels. The gun is in very nice condition but the barrels seemed tight in diameter when I measured them a few years ago. I can't remember exactly what they measured but remember thinking the bore was on the tight side for a 16 gauge. Is it going to be okay to shoot the above slugs through these tightly bored barrels? I expect it will be okay but just wanted to get the helpful opinions of the board members here first. And I think I remember hearing on this forum that there was a standard barrel that was traditionally loaded with a slug. Was it the right barrel or left? Thanks, Ron
