50-90 Sharps was originally designed for blackpowder, this obsolete vintage cartridge is again rising in popularity due due to the increasing participation in cowboy action shooting and blackpowder silhouette competitions.
To Be Determined
* Starline Brass does not sell any loaded ammunition. What you are purchasing are brass cases only and will need to be loaded into ammunition in order to be fired from a firearm.
I bought 20 rounds to start testing, I wanted to reform this case to a 45-75 WCF (obsolete cartridge). I cut 1/2" off case approximately, then ran shortened case through a RCBS 45-75 WCF FL sizing die. It went smooth as butter, I re-formed into 45-75wcf in a series of five strokes. Only about 1/4" each time. 5th stroke finished it off. Trimmed them all to 1.895", from there I turned the .650" rim dia. down to .627-.628" they all cycled through my Uberti magazine tube fine. I will be ordering another 400 pieces very soon. Thank you for making these available in good quantities. Great product. I also have your 6.8SPC and 45-100 brass as well, all super quality cases, well made and meant to last. Anneal them and you will have re-usable brass for a very long time.
