No WANO PP this time, but Pyrodex P.
Here are the load data:
Reformed .348 Winchester cases.
Winchester LR primers.
38 gn(by volume) of Pyrodex P in stead of 45 gn WANO PP.
A cardboard wad and a bit of cous-cous as a filler.
A 320 gn bullet on top of it all.
I used Pyrodex P in my Dutch Beaumont before and I hope the results will be equally good with the Vetterli.
Got some range time coming up on Sunday.
I'll keep you all posted.

.........a cardboard wad and a bit of cous-cous......
Met vriendelijke groet,
