Hope it’s of use for you, because it reflects European reloading stuff.

All cases are RWS. Some bullets are .366 diameter but the load is CIP proofed for it. (2000 bar hmp) (29,000psi)

Sorry for the jumble but I copied from Word files I made up. No primer is given. The article contains some important information about the loads overall. The standard bullet is 193 grains. I bought two boxes of S&B ammo from Joe Martinelli on the drilling hotline. Just google drilling hotline and take a look.
I hope this helps.
