Hi sorry for such a late reply. I bought a CZ 527- 17H. Although I haven't used it much so far, l will soon. I've got N110 and N120 powder. I've only used N120, starting on 10gr and increasing in .1 increments up to 10.8gr. Not a bad group with 10.8.
I have not chronographed it yet. What do you suggest, should increase the load? I've got also 15.5gr as well as 20gr bullets. Any recommendation for loads on them?
