Scope Zero Check Thread

[Mw01313]

What rifle and scope?

It's an older Ruger American Predator 6.5 CM in a MDT field stock. Scope is a Zeiss V4 4-16x44 in a set of Vortex rings.

I had previously relied on a ten shot group for zero, but decided to see what a 20 shot group would reveal. Rifle is a Jon Beanland built Zermatt Origin in a McMillan CF Game Hunter stock with a 20” Bartlein 3B chambered in .308, with a US Reaper suppressor. Scope is an Athlon Helos BTR Gen 2.



1st shot was encouraging.



Next 19 were fired five at a time, letting the barrel cool long enough for me to walk down and check the target.


Indeed, the higher sample size, though close, is not a perfect match to the 10 round zero. I adjusted .1mil up, slipped my turret to zero and called it good.

Are you sure the image displacement from a hot barrel creating mirage didn’t cause the downward trend, we see this all the time here shooting f class and compensate accordingly.

I don’t think so. IIRC, the second shot was close to the center of the group. It wasn’t a gradual trend downward, just random dispersion.
