6mm TCU

[Flyeralan]

I make them here, but it has been a while. Made correctly they have lasted through many loadings in my contender custom shop barrel. The only mistake I made is trimming them to length before fire-forming them and they ended up a little short. Still been using them for quite a few years. I just used new commercial brass, I think Winchester, but would have to look to be sure. If using anything used, I'd just anneal before forming them.

I have a 7 TCU contender barrel, but when I bought it, it came with a bunch of brass. I didnt know exactly how the process worked. Did you fireform with bullets or some other type of wadding?
