.360 2 1/4 cases were available at www.buffaloarms.com made from Rem 30-40 Krag brass, but not listed in last catalog. I have 160+ .360 2 1/4 cases I made from Rem 30-40 Krag brass that has .053" rim thickness instead of .046 as most of the books state. After I made these cases I found the chambers in my Wm. Moore & Grey are 2 5/16", so I made new longer ones. The base dia. is .434" witch slightly larger than the books call out. These cases have been fired about 4 times with BP ,washed & cleaned with walnut hulls. They are for sale.
