Tikka pic rail question

[peterk123]

I got a Tikka t3x lite in a 223. I will mount a pic tail on it so I can pop a thermal scope on and off it easily, as well as a regular scope. Gun will be used for prairie dogs and coyote, out to maybe 350-400 yards. Would you go with a 0 or 20 MOA? I'm thinking 0 but I'm guessing. Not really sure when a 20 comes into play. I'm guessing much longer distances.

I would stick with 0 MOA. Most of the people I know who use 20 or 30 MOA rails are shooting rimfires at 300 yards.

Zero

20 moa for long range stuff

0 moa.
-same as a standard ar15 rail for reference.
-77gr TMK starting at 2700fps, 100yd zero, starts to go transonic at about 10mil of elevation (roughly 950yds at mid density altitude give or take).
-most 30mm scope tubes give +/-15 mil of adjustment travel from dead center. You’ll have plenty of adjustment to take 223 out to transonic speeds, and then some.

Finally, if the rail you want is only available in 20moa, just get whatever is in stock. You’ll have no functional difference using the scope or thermal.

Using a 20 MOA rail pushes the turret down for close shots so when you shoot at long ranges the reticle/turret is in the middle of its range.

The thinking goes, if you are shooting close most of the time, the 0 is better because the turret will be in the middle. If you are shooting long more often, then you want 20 moa to get the turret in the middle at long range.

Getting to the extremes on the turret may create issues.
