There were 409 #8s per ounce, so 300/409 = 73.3% and 295/409 = 72.1%
I believe the 16-gauge guns were targeted with 1 ounce of #8s, but have yet to find a hang-tag to confirm that. My two 16-gauges are marked 293 (71.6%) left & 288 (70.4%) right, and 301 (73.6%) left & 246 (60.1%) right.
The pellet count tables in the Remington Arms Co. catalogs of the period give counts for 40%, 60% and 75% but show patters labeled Cylinder, Modified Choke and Full Choke.
Just to keep us confused, Remington Arms Co. put recommended maximum powder charges on the back of their hang-tags for all three gauges, but no mention of shot charge?!? This tag shows the old Laflin & Rand dense smokeless powder --

By this tag they have moved on to the L & R Infallible --
