Thread: .17 Mach IV Barrel

Nice write up, I assume that's a typo that the 25gr are doing 4200, 20gr I can see at about that. not 25gr.
I have struggled with both my chrony's, to get consistent readings, on the 20gr weight, I gave up fiddling with settings, after a while, point and shoot to 250m, explosive results on small game, a ground squirrel, rat or magpie, simply disappear, and rabbits, hares are just a smoking ruin.
Mostly I prefer the 25gr, bit better at long range,
Anyhow, nice info, and enjoy your rifle.
