38-55 brass

[JKR]

A year ago I started to work with an original Highwall 38-55. I was lucky enough to get 50 pieces of brass at that time but have been unable to find any since. I have backorders with both Starline and Track of the Wolf.
Anyone out there know where I can get ahold of any of the longer length Starline?
I’ve found the 38-55 to be a fun rifle for the informal gong shoots in the area. My 50 rounds isn’t quite enough to get through a match.
