I would say your pricing is fair. 44-40 is sort of an oddball cartridge. It was Winchester's first smokeless cartridge, and it is designated as a rifle cartridge that was also used in revolvers.
The ammo is ridiculously expensive.
ADMINISTRATOR... Can you please remove this ad. I went to the range today and the 44WCF would NOT fire. I used 44/40 RIFLE ammo. Need to do more research. Sorry and thank you.
