Gents,
A while back I too was wondering about pressures of various loads markets as "light," so I sent 10 of them (5 shells per load, for averages) to Tom Armbrust.
If you follow the link to the Lefever forum I imbedded it in that thread.
You will note that Winchester "light" loads are really only so compared to standard modern loads. But they aren't light by vintage standards.
I sent him RST Falcon Lites to use as a baseline, as I was curious as to which of the more widely available majors might come close.
See for yourself...
