Thanks, Skeen. That's the most recent info I've seen on the Pacific rifles. When I see that Renner has a "TM" by "Genuine Forsyth Rifling", I get the slight whiff of a huckster.

The best article I've found on Forsyth rifles/rifling was by Ross Seyfried in the old Blackpowder Hunting magazine. It must have had some influence on me, as I bothered to save it. The deer I killed last month was with a lovely Steve Zihn-built English style .62 caliber rifle that has Forsyth style rifling; a Moody barrel if I recall correctly. Based on its dimensions/architecture alone, I'd take it over any of the Pacific Zephyrs/Faetons I've seen pictured.
