Mike, I use to test Volume vs Weight Grains fairly often just to see if it changed much between cans of powder? I finally Quit doing it, Volume And Weight Grains are SO close with this Swiss, many times Identical
But Since you asked, and i haven’t Tested Volume to Weight Grains in a VERY long time, I thought I’d check it again and See what it came out at? I’m pleased to say it hasn’t changed any since the last time i tried I just filled 80 Volume of Swiss 2F and checked it on my Weight Scale, I got 79.7 Grains
