M D N Updated

8x50mmR Lebel came in three major flavors.


 

I mentioned that GURPS gave us stats for what appeared to be the Lebel in Balle M, Balle D and Balle N, recently

To repeat (Edited):

High Tech gives 6d pi, 900/3,900.
Adventure Guns gives 6d+2 pi, 800/3,300.
Pulp Guns gives 6d+2 pi, 1,000/4,200.

I think that Pulp Guns, which represents the interwar period, could be either the Balle D or Balle N.  Adventure guns covers the Victorian era to WW1, so it's more likely to be Balle M.  High Tech isn't time specific, but mostly gives the stats at the introduction date, so it's prolly Balle M as well. 

Gun Stats gives:

Balle M (1886) (232 gr, 1.2" long bullet at 2,060 fps) 6d+1 pi, 920/3,900 <- very close to High Tech's numbers!

Balle D (1898) (198 gr, 1.54" long bullet at 2,300 fps) 6d+2 pi, 1,080/4,500 <- very close to Pulp Guns numbers!
OR
(198 gr, 1.54" long bullet at 2,400 fps) 7d-1 pi, 1,120/4,700

Balle N (1932) (231 gr, 1.54" long bullet at 2,200 fps) 7d-1 pi, 1,200/5,000
OR
(231 gr, 1.54" long bullet at 2,300 fps) 7d pi, 1,260/5,300

Assuming that the Balle N bullet is identical dimensions as the Balle D, just lead core instead of solid brass.

I've found contradictory sources for the muzzle velocities for all three rounds.
