Hello, found this UMC .44-40 casing on an Arizona ranch. Does anybody know when it dates to? I know this size of bullet was first introduced in 1873, according to what I read on wikipedia, and the Remington and UMC eventually merged. I know its old, and I am mainly interested in knowing when UMC or other ammo manufacturers began using headstamps on their ammunition. But any info on this casing in particular would also be appreciated. Thanks
