4 Gauge Brass Cartridge

I just got this empty primed shell and was wondering about it. It is primed and appears (new) never to have been loaded cause the inside is very clean, looks nice and coppery on the head inside. The headstamp is small Remington and lareg UMC at 12 oclock, 01119 small and No 4 large at 6 oclock Please see picture…also what are the numbers above No 4 about. The casing is 2 3/16 inches long and made of all brass. Any info is welcome…THANKS I am from North Dakota I tried to post 2 more pics but it would only let me post one. Please see other post for head and headstamp
