Again, this is an original Winchester 1873 24’ rifle made in 1888 in 38 WCF. Both the Ohaus (rcbs) bullet and Lyman bullet were probably water hardened wheels weights sized to .401. True, I have nothing to loose letting them aircool at maybe 12 BHN compared to 20 BHN water hardened. The Ohaus bullet has a proper crimp groove for when I am using smokeless powder so I need that for cowboy action.
