Charlie, when Winchester introduced the Model 42 in the early '30s, they or Western, announced the new 3" shell with a 3/4 ounce payload. Only in the past few years, has the 3/4 ounce load been available, again, from Winchester-Western. Ideally, the payload of shot should be 'square'. That is to say, that the height of the payload should be as close to, or equivilent to the diameter of the payload. The 16 bore has been touted as probably the most ideal shotgun because of these dimensions. Even the 3/4 ounce .410 is disproportionate in regards to the height of the payload compared to the diameter. Increasing that load would not help performance. That may be why a 1 ounce load has never been marketed.
