What castnblast, erich, and gunscrew said.
Nothing wrong with saving a little lead making 7/8oz practice loads. But for most 16ga hunting with lead shot, imo, 1oz loads, 1150-1200fps, shot size per application/preference, is a point both effective and efficient. You can make ‘em 1 1/8oz, sure, if you desire. Ymmv, but this stuff has been studied, sorted and well-commented on for 50yrs or better, and aside from non-toxic shot combined with heavy payloads striving for an extra few pellets at distance for some waterfowl via souped up 12ga loads (in an effort to mimic the now scarce 10ga) - there’s not much new under the sun to re-invent.
