Using two different methods, and making several passes with each, I measured the chamber lengths of an early 16 gauge Ithaca NID to be something between 2-5/8" and 2-11/16". Does that sound right? I know nothing about these guns, but would have expected either a much shorter chamber, or a full 2-3/4".
I'd like to try some light, low pressure loads in cut-down plastic shells, using felt and card wads for starters. My thought was to experiment with eight or ten rounds, loaded by hand with a ram if I can come up with a few sized hulls. I don't own a 16-gauge press.
Can anyone recommend such a load for 3/4 and 7/8 ounce shot? I've got mostly Hercules powders in stock and would prefer to use one of those. For the number of shells I will load, weighing individual charges will be no chore. Unless someone advises differently, I will plan on adjusting wad pressure with the old bathroom scale trick.
Can anyone tell me the safe operating (chamber) pressure for this gun? I believe the piece was manufactured in 1926, pointer lightly engraved on sides of receiver, cocking indicators.
Will be grateful for any advice and input.
