Well guys, after taking some of Indy's advice I loaded several hundred rounds of .40 and .45 and built of the courage to load some .223. Now I see why you guys advised in that direction. Bottleneck rifle is MUCH more involved. I finally got my first 200 rounds loaded but only after some very aggravating experiences. I broke off two decapping pins before learning that it was my brass that was causing the issue. I am using Lee dies if that matters. I discovered that the flash hole in this stuff is smaller diameter when I tried to trim it to length and the pin wouldn't go in. I've got some pics of the brass and I hope one of you guys can tell what I can do to reload this stuff. Seeing as how I have about five hundred pieces of it. The first two are a comparison of the unfired and spent casing and the last is a close up of the bottom and headstamp. Wanna kill these ads? We can help!
