There were three different loadings in British tables : high velocity with 1 oz, standard velocity with 1& 1/16 oz, and low velocity with 1& 1/4 oz loaded with nitro powders. However the Black powder standard velocity was a 1& 1/8 oz load. Having said that - if memory serves - the Eley Alphamax 3" load (smokeless powder) was a 1& 1/8 oz load.

Interestingly, Burrard shows each of the three velocity loadings with either 33 , 36 and 42 grain powders - as well as with condensed nitro (Ballistite).
