................if Kirst had those,....it would be called a Ported Converter Ring without
the loading gate. But heck, maybe you could port the Drop-In converter ring yourself, like Marshall suggested. I wonder if that's what Charlie did?
Tizwin,....As far as using the Schofield case in my R&D ( I don't use any Kirst cyls. at the moment) ....I noticed what Grapeshot did,... about the Schofield rims being slightly larger, and what I did was take a dowel that would just fit inside the Schofield case, ...put it in the drill press so's I could slip Schofield cases on & off it while the press was runnin,...and then slip Schofield cases on the spinning dowel,..touch the rim of each case with a fine metal file a bit,...just enough to bring their rim size down to fit into the R&D rim recesses. Worked good!
I like shootin the Schofield round in my Uberti '58 Rem with the R&D cyl.,......27gr(weight) FFg Goex under a 200gr soft lead Big Lube bullet, lubed with Dick Dastardly's "Pearl Lube".........a pleasure to shoot, less recoil than a full house .45Colt load........but plenty of smoke & boom and pretty accurate.
Nice large lube groove on the JP-45-200 holds enough lube to keep the cylinder cycling smoothly for many re-loads, ...with an occasional drop of Ballistoll/Water mix at the front of cyl. at pin ifin things get sluggish. The JP-45-200 Big Lube bullet and the .45 Schofield case seem to be a perfect match. I picked up a six-cavity mold from Dick Dastardly so's I could cast my own,...here's a pic of a few of 'em that wanted to pose for ya.....
Also,...here's an article about the bullet and its designers..........http://my.net-link.net/~napfn/jp45-200.html
