Hey there, I'm new here. Was wondering if anyone knows of factory loads which Winchester uses their 572 powder for 20ga? Reason being, I've cut open a bunch of random Winchester shells to weigh the components inside, etc. I have yet to find one of the shells I cut to have the proper powder load for 572. They're usually all WAY higher, at leas 4+ grains. Wondering if this means Winchester errs on the safe side when giving out load data? And do they load stuff way hotter than "we" should? Or do they not use 572 that often, even tho it's an excellent powder?
I've been using this powder for my buck and ball 20 ga load for over a year now and I love the powder. Just wanted to compare for the sake of it. But I can't seem to find any info. Thanks!
