Hi all! New to the site.
i use a CZ varmint 16" with Wildcat whisper mod & Nikko Sterling Gameking 4-16 x 50 AO & Harris 9-13 swivel bipod. Have had it for about 18 months & cant rate it highly enough. The last pic is what it is capable of shot at 100 yards off the bipod.
I've not found any brand of ammo any better than the next but always re-zero when changing batch/manufacturer, although the difference is minute.
The only difference i have noted in the .20 gr XTP over the .17 gr polymer tipped is that the .20 XTP go straight through everything so i now only use the .17gr.
