I've tried every factory offering made in my 204, nothing would shoot better than about 1", so I've got some of Mitchell's BL-C2/40gr Vmax loads loaded up, just need some range time with it.
I would have handloaded to begin with, but brass was all but impossible to buy in 2004 when I bought it, but with all the factory ammo I've shot in it, I have lots of brass!!!
Yours seems to be doing well, keep at it!!
