No, not yet. Have to wait for the pension cheque to get here so I can develop one!
However, Barnes in CARTRIDGES OF THE WORLD - 6th Edition, gives:
46 grains of 3031 with a 198 for 2310 MV and 2358 ft/lbs ME
45 grains of 3031 with a 206 for 2300 MV and 2420 ft/lbs ME
FACTORY LOAD with a 206/8 for 2034 MV and 2233 ft/lbs ME
Considering the factory levels with this round, I really don't like the idea of going almost 300 ft/sec faster with a 208 slug.
On the other hand, the original stuff WAS loaded with a square-flake powder which would not burn as progressively as the IMR types.
Still, I don't think I would exceed these loadings: my arthritis is quite bad enough now!
If you are loading for the Carbine or the Stutzer, it would be a REALLY good idea to stick to quick-burning powders, although you might go to a more progressive powder for the longer Rifle.
Still, the original loading for the 1888/90 cartridge, with its slightly-smaller case, as used in the Model 95 had a 244-grain slug popping out the muzzle at 2030 and the commercial loads ran at 2100! For power, these pretty much equalled a .303, but each time with a heavier bullet, going a bit slower.
I HAVE fired my Bulgarian 95 long Rifle with original Bulgarian 1944 stuff and can state (most authoritatively, my shoulder tells me) that recoil is definitely there!
Have fun with the toy and let us know how things come out.
Be nice to see a few more of these back on the ranges.
