HMR basic practice

Back out with the HMR after a bit of a break. I have taken off the Nikon and put the Bushnell banner back on. Before I start on vermin control with it again, I need to make sure I am still competent with the adjustments etc.
Today I am just shooting at a 10cm target at 190 yards to pretty damm easy with this rifle, but that is how I will build back up again, checking my data still remains the same.
The rifle is a CZ452, 16" varmint barrel. Ammo is Hornady 17gr vmax.
For those who don't follow me regularly, the reason I gave swapped scopes, is that I have put the Nikon on my CZ 527 .204.
