Volunteer Proof of 3,7 grammes of G.B.P. pushing a Steel jacketed projectile, where G.B.P. denotes the use of a military flake powder called Gewehr Blättchen Pulver. I know that 2.67 G.B.P. produced a pressure of 58,800 psi, but I am unsure of the pressure for 3,7 grammes. I would assume it was non-linear.
The Volunteer proof was added to the law/rules on July 23rd, 1893 but one really doesn't see widespread use until after circa 1900.
