The Zero Check Thread

Put a different scope on and the brass is once fired now so wanted to see how that shoots…
Dot is 1.1cm

Looks like a precise system... have you made any adjustments to set zero? Interested to see how it holds. What are the scope & mounting etc details?

Going to leave it as it is. Checked it at 430m. Had to make adjustments to the BC to get it to line up.
Talley lightweight rings Swarovski Z5 on a T3x. Will be interesting to see how the Swarovski holds up.

Hmm interesting. What bullet are you using?

6mm Creedmoor 108eld-m. Thinking about it the swarovskis are known for not tacking true to MOA so could well be that?

The cut-rifled match barrel clearly gives the expected results !


At 430m you'd have to be using a tremendously wrong BC value to see any difference in drop - it's substantially more likely a variable input issue in the app or scope tracking error.

I've used Applied Ballistics and 4DOF default values for the 108 out to well past 800m with no issues

I’d go with the scope tracking error. Had a Maven on to start with and it was spot on tracking wise. I found it a bit chunky is the only reason I changed. I’ve come to like mil’s as well.

Aren't the z5s something like .975 inches at 100 yards instead of true MOA ?

I believe you’re right. I’ll have to have a play around with my Shooter app. Thanks.

Hey Zeb, there's a setting in Shooter (rifle set up) to change the elevation unit to IPHY (inch per hundred yards) and then set the Elevation correction factor to 1.025 has my swaro on point
