My hunting rifles go with to the range once a week for a month(after load development/zeroing) for a single shot. Using same target, if I see a shot impact that doesn't fall into group/zero I do a box/tracking type test, after checking any screws on the whole rifle that are torqued. Currently doing this with a rifle for elk season, will carry it suppressed, checking to see if removing/installing suppressor has any zero shift possibility. So far, 3 range trips with suppressor on/off, no zero shift. Rounds are just making the single hole bigger.

Light refraction/water vapor. Humidity.

Search for “scope checkers”. IMO it’s the best way.

Coyote
What type of rifle ,stock barrel contour and length, and how is it bedded?
What suppressor and weight and lengths?

Sounds like a well built rifle.

This is pretty much what I do. As I belong to a private rifle club about 30 minuet's from where I work, I keep my three primary hunting rifles in my truck (extended cab) at work (park in fenced areas in key card drive in gates manned by security 24/7) once my load development is done I drive to my range after work literally take one shot at 200 yards confirm zero same targets then put 3-4 mags through my CC/HG or HG's of choice and call it good. Do this two months leading up to gun season.

If heading out west for an elk hunt it is a little different.

The rifle is a TC Icon in 30TC, shooting a Barnes 165 gr tipped bullet @ av 2780 over Ramshot xterm (42.8 gr) "Real wood stock" Harvestor suppressor. Sightron stac scope. McCarbo replacement trigger spring. September will be all 300 yard practice (longest target at my range). Rifle has been on 2 elk hunts, one bull and one cow, both one shot drt with 165 gr Hornady SST. I hunt DIY on public land. At 64 I guess I will find out if a self pack out is still possible,as the rest of the elk hunters in my group have quit (much older than myself). All my elk have been under 200 yards, most under 150 yards. I don't imagine that will change this fall.

Doc, here's an example of the box test:
Box Test
Try shooting the box 3 or more times and see if you get consistent groups at each corner of the box. I would think if there's an issue with the scope internals that it would show up with this test.

Borrow my Hood scope checker Doc.
