This thread started my thinking,
a couple of years ago I purchased a British Enfield MK II Revolver.
It's a 1943 manufacture with a Canadian broad arrow mark. No other import marks.
The Cyl. throat Mic's @ .361 and the bore is bright with strong riffling.
I have shot it with .38 S&W, I have on hand for my 1919 Colt Police Positive.
Bunk sent me some primed 38 special cases cut down to 38 S&W/ short length.
I'm giving Matt's bullets a call to order
200 Grain Long Round Nose Webley MK II (.361)
This bullet copies the profile of the British MK II bullet for the Webley and similar revolvers chambered for the 38/200 cartridge (38 S&W)
Choice of powder will be Trailboss looking for + or -
750 FPS
Pays to proofread 650 fps was typed... I knew that I blame fat fingers

Doh

I also know it's an Enfield I cut and pasted
