Hey guys, first time to the forum since the crash, had to re-register and everything.
Anyway, got tired of burning up expensive powder and bullets, wearing the barrel, etc. just to fireform cases. I setup a CNC lathe and turned a pile of delrin bullets that are about the size of 100 grain bullets. They have a slight boat tail, mainly for ease of loading as I could care less how they fly. They weigh 13 grains.
Used Quickload as a rough guide and ended up with a load of 8 grains of IMR Trailboss and a OAL of 2.170.
I was able to fireform a bunch of Privi brass today without a range, without barrel wear, and with a very minimum component cost. Just put the muzzle into an old pillow on the back porch and fired away. The action does not cycle, the brass does not eject.
Cases are fully formed, checked with a mic all along the body. Only difference I can tell from the "real" fire formed ones is that the shoulder isn't as crisp, little more radiused. I am going to order a bunch more material tomorrow and do a big run of these, they are really handy!
