The rear lug is marked 40 for the right barrel and 48 for the left and I see no indication anywhere that anything but the "standard" #8 chilled was used. The heaviest 10-gauge loads UMC offered were 1 1/4 ounce so -- 340/511 = 66.5% and 348/511 = 68.1% or about improved modified in both barrels. Hard to say if someone opened the chokes a bit or just targeted the gun with some other load and got modified patterns. I don't have the barrels in hand to run a bore mic in them, and even if I did, I have no data base of Remington Arms Co. 10-gauge bores to compare the results to.
I've long wanted a high grade 10-gauge Remington Hammerless Double, but I've never seen a 10-gauge above C-quality and the "right" gun just hasn't come my way. Is this the CEO-Grade 10-gauge the one Ben Loving had for sale a score or so ago?
