A few years later UMC sped up the 10-gauge loads a bit with up to 4 1/4 drams of bulk smokeless powder or 34 grains of dense smokeless powder such as Infallible of Ballistite pushing that same 1 1/4 ounce of shot out of their ARROW shell.

I suspect it would have been 1 1/4 ounce for testing in the Remmy 10's, but what shot size? If they used 7.5's instead of 8's the numbers translate to a higher percentage i.e. a tighter choke.
