You are only the 10th person to request that in over a years time. Unfortunately, it is not a casing we are perusing to manufacture. @jgraff08 Only the 6th request for 240 Wby, also not one that we are perusing currently. Sorry!
Yea I don’t think most people even know what it is anymore. There are a lot of 257 Robert’s rifles out there though. I see them in the used racks all the time. While it might not sell like the latest fad cartridge it’s been around a long time, the guns exist, and current brass options suck.

Just make the 20 people that want 6.8 western a day of brass so we don’t have to hear it anymore. Then roll on to 223!
Honestly idc if they do I'll use win brass in mine but if we could alternate the 2 yrs each place would run it right it would work

How many firings can I expect out of the 300 win mag long cases? I'm not firing over max charges, nor do I intend to. I'm working within stated reloading data. I believe I'm on my fourth firing.
While we cannot guarantee any amount of firings due to the variables from setup to setup, we do test fire our casings out to 20 reloads in-house! Using our 300 Win Mag Long casings, if you are meticulous with only a 0.001-0.0015" shoulder bump after the virgin firing, you will likely be able to obtain more reloads than any other Win Mag casing on the market before seeing signs of head separation!
