Ok, so I got to shoot it this afternoon for the first time. Things went really well
I first fired a box (20) of PPU 100gr soft point hunting bullets. PPU are never loaded terribly hot and I wanted an idea how the fire forming of the cases was going to go. It went pretty smooth. All 20 rounds went into about 2" after I got the scope sighted back in.
After that, I cleaned the bore with hoppes and some patches. There was very little fouling and almost no drag on the patches. Then I started on the reloades I made last night with Remington Brass, CCI primer and Hybrid 100V powder. The Berger reloading manual gave the powder range as 39-41gr of 100V for the regular 243Win case. The Hodgdon website has the load listed from 39-43gr which is supposedly a compressed charge. So I decided to run with 41gr since I knew that pressures would be lower due to the expansion of the case into the chamber.
Here was my first group, including 1 sighter (POI shift from the PPU to Berger bullets) this was 6 rounds.
Here was the second group this time 3 rounds
So much for Berger being a bear to get to shoot.... Of course final loads will be hotter with fireformed brass, but for now I have quite a lot of brass to work through with this load. Not sure I will go any hotter until done with fireforming.
I also shot my CZ 512 in 22 mag. It only has a 4.5 scope, which does not do me any favors at 100 yards and the wind was blowing too.. My gun consistently fails to reset the hammer at least once per 5 rounds. I have to get that problem figured out or I will be looking to get rid of it. I waited so darn long to get it too....
