barrels:quoting here:
"It is said to push a lead bullet through the bore and measure it to know exact diameter as they may vary.
I recently acquired a beautiful Model 1892 French Ordnance revolver with a barrel date of 1922 [ S 1922 ]. The bore is bright and shiny with well defined lans and grooves. However, the barrel slugs at .312 - .319.
On my two, they both slugged .323 groove diameter, so I resized my .330 graf bullets using a lee sizer to .323, in fact my chamber mouths are only .324-.325 so I don't know how a .330 would get down there without undue pressure, my fiocci bullets mike around .320.
My understanding is that 8mm Lebel (revolver) should be .330.
My own ...bullet .330 came out at .326 so bit tight not as above post but still tighter than .330. Factory was .323
Please do not attempt using .32S&W long. It will fire but the case diameter is too small and will bulge. Not a safe thing to do.
Use oiginal brass or trimmed 32-20 with lead .330 bullet. die set can be found from mystic precision Hrn at $84 per set , also RCBS has the dies available special order as part number 56917
one source:Quoting
I used Starline 32-20 brass trimmed down to 28mm, a cut down lee .308 trim mandrel and a drill worked good. I then ran them over .323 ball and then over a .330 ball. After opening up the neck the brass measured exactly 27.5 Loaded a .330 diameter jacketed 100 grain bullet over 3.8 grains of unique, fired by a CCI sp primer. After the first firing the brass looked handsome and required just a little trimming to get it back to exactly 27.5mm. After 3 firings the case mouths are fine. I tried as much as 4.0 grains but that was a little more snappy then needed for plinking. 3 grains would not push the bullet out the barrel.
from another source:
115 grain bullet, 2.8 grains Bullseye, MV 700 fps, ME 126 foot pounds. They used the Lyman # 32359, which is the standard 32/20 115 RNF bullet.
here is CGN experience in loads:
2.8-3.3 unique... someone as much as 3.5, 3.8 and 4.2 (that's hot)
2.8 bullseye
11.0 FFF goex BP
2.8-3.2 win 231 would work... did someone try this?
2.4-2.9 trailboss
Tested trailboss myself... 2.5 gn is good start, anything less at 2.2gn and bullet sticks into 2x4 and you can pull it out by hand. Then increased the load to 2.8gn. Worked well but little hot and... at 2.5gn gun hits POA, with 2.8 its about 3" high and no reason to beat up on the gun.Trailboss fills the case nicely no chance for double charge.
These were .330s from EE. Good soft bullets, but chambers on my gun are tight and they don't fit so need to re-size them smaller and see..for now just sanded a bit till they chambers. Worked well and accurate as hell. Good buy. Other guys had better luck with them. Barrel was measured to .326 that's why is a bit tight.
