In the "interest of science" I preformed the following test.
One (1)empty 38 SW (Win Super X Nickle) $30 a box
I guesstimated half a case as I did not want to pull a loaded 145 gr heavy crimped LRN
It holds 2-2.1 grs of Trail Boss depending on how many little Doughnuts float away!
I think Bullesye or HP -38 would actually push the bullet out the barrel.
Reminds me of the first time I ripped open a large bag of
Splenda thinking it was like sugar. Lost about half of it.
