I know that cheap hulls are rarely worth dealing with but I have been given over 500 remington hulls I cannot ID. One is 20 gauge yellow low brass 6 sided crimp 2 3/4 length. It is all plastic (no paper basewad) marked 2 3/4"-70 mm up the side and 2 1/2-7/8-8 across the top. The second is 12 gauge black low brass 8 sided crimp 2 3/4 length. All plastic marked same as 20 gauge up the side and 3 1/2-1-8 across the top. Both are brass plated steel heads. Any help with ID will let me use these for casual shoots at family get togethers where many are lost and so I am not out of anything getting one reload then discarding or losing them.
