A friend shoots an original Winchester '73 .38-40 at our NCOWS cowboy matches. He reloads with 2F black powder only. He has indicated to me that in reloading, the whole neck tension thing is something that requires a lot of attention to get right, just like .44-40. He lubes cases for resizing as you would expect for any bottleneck cartridge. The Starline cases have performed well for him.
