While waiting for my reamer I decided to practice forming cases. I have some old Winchester 243 brass shot numerous times. Following the instructions I was able to form this brass correctly. It took some practice and some of the necks split but it is old brass. It did come out shorter than 2.025" but it may have been short when I started.
Emboldened by my success I opened a package of new Winchester brass and went to work. Well after 25 cases it is s disaster. Every one has a ridge indent around the case just below the case / shoulder junction and the OAL is shorter than 2.025". I tried more One Shot, less One Shot, let it dry over night. I even tried my trusty Imperial Wax. Nothing changed. One of the reasons I selected this wildcat was because it is advertised that fire forming is not necessary. Do you have any suggestions? Thanks.
