Strange bullet but #1 looks like a 7.5mm Swiss, #2 looks like a 38 long Colt outside lube (NAVY), #3 is up to greater minds than mine.
Keep um coming. I’ll keep trying.
your #3 is for a .303 British adapter, used for indoor (range) shooting & not in a revolver.
The first one is a 7.5 Swiss revolver cattle killer relaod made by an unknown gun dealer in Switzerland many years ago. I have never seen a box.
