I'm re-keying the information that I lost on my crashed laptop... Sort of slamming it out.
The Winchester Single-Shot, Volume II, by John Campbell. page 91. ISBN: 0-917218-91-4
Added the Rim and Base diameters to the list, maybe someone needs to get an idea of dimensions for a unique chambering... Please confirm these Rim / Base diameters [plus rim thickness..] BEFORE you start machining. I have no measurements of the extractor "tip" where it extends over the top of the rim. Winchester also stamped extractors with the cartridge [instead of these #s].
NOTE: the .22 rimfire extractor extends across the bottom of the rim in a "U". Centerfire extractors are in a corner of the breech face.
Receiver #2 [Low-Wall].
Rim / Base / Ext # / Cartridge
.278 / .226 #4 22S/L/LR
.333 / .276 #5 25 Stevens R.F.
.378 / .315 #6 32 R.F. - 25/20 Single Shot & Stevens
.342 / .295 #7 22 W.C.F.
.408 / .354 #8 32 Ideal - 32 W.C.F.
.525 / .469 #9 38 W.C.F. - 44 W.C.F.
On page 94, John says you can use High Wall extractors in a Low Wall, but they will extend 1/16 below the receiver. All mounting holes have the same dimensions and placement.
Receiver #3 [High-Wall]. Note the "14-19" extractors are the same cartridges as for the Low-Wall.
Rim / Base / Ext # / Cartridge
.278 / .226 #14 22S/L/LR
.333 / .276 #15 25 Stevens R.F.
.378 / .315 #16 32 R.F. - 25/20 Single Shot & Stevens
.342 / .295 #17 22 W.C.F.
.408 / .354 #18 32 Ideal - 32 W.C.F.
.525 / .469 #19 38 W.C.F. - 44 W.C.F.
Receiver #3 [High-Wall]. Some case dimensions do not allow these extractors to be used in a Low-Wall.
Rim / Base / Ext # / Cartridge
.506 / .422 #20 25/35 W.C.F. - 32/40 - 38/55 - 30 W.C.F. - 32 W.S.
.539 / .457 #21 30 Army - 303 Brit. - 35 W.C.F. - 405 W.C.F.
.610 / .508 #22 33 W.C.F. - 45/70 Govt. - 45/90 W.C.F.
.607 / .551 #23 50/110 Ex
.661 / .579 #24 50 Eley [also known as 500 BP Express]
.660 / .747 #25 577 Eley [used .577 Snider dimensions]
.766 / .697 #26 20 Gauge
