POI shift ?

[Vana2]

Well it's not practical in real life which to me would be either a match or a hunting situation to shoot a 50 shot warm up. But given you have a 50 shot warm up target to me you obviously need a click or so down. Windage looks pretty good although shot with no flags is suspect. What would be interesting would be to shoot the same format several days in a row with no scope changes and see if the results are parallel. Even better if you did it with at least one flag do you don't shoot in any reverses but in similar conditions. Shooting your individual dots shows more pertinent information than shooting groups. Good thread. The information you have with your target needs to be gathered with maybe 10 shots or less at a timed competition.

Most of my shooting is off-hand plinking and that is how I warm up / loosen up for a bench session or tuning and testing. Pesting and hunting are cold-bore by necessity.

I shoot the report cards to establish baselines and for the fun of it. I do compare report cards. Shooting a week long series is a good idea though it would result in major complaints from the other residents of the gun cabinet

I usually pause between shots to reflect, jot down chronograph numbers and force a reconnect/refocus so that each shot is a separate event. Your suggestion of rapid-fire timed targets could be a fun exercise as well.

Cheers!

I do believe your are mistaken.

1/4 MAO at 100y = .26 inch
1/10 mil at 100y =.36 inch

Ipso Facto, one click on a standard MOA scope is smaller than 1 click on the standard 1/10 mil scope.

It matters not what a scope will "show" in this question, rather how far the cross hair moves for each click. The "show" would be a matter of zoom power.

I was referring to a 1/10 MOA scope and not a 1/10 MIL scope.

In other words 1/10th of an MOA.

Thread title: POI Shift?
The original purposed question by the O.P.
“But from day to day or whatever time frame you pick is it that uncommon”?

For the experienced, educated skilled shooter, employing quality equipment, ammo & wrote technique “Yes it is uncommon”.
The greatest challenge lies in compensating for atmospherics which will indeed change your POI most noticeably at distance.

Shooting in the same location, under like conditions, I have never experienced POI shift with quality equipment. I have hunted game with a kill zone the size of a walnut for 50 years at distances out to 150 yards and never experienced a noticeable POI change wether it be an airgun or a PB.

As to parallax - my scopes have no adjustment for that nor is it needed or even desired in my application. The scope has a fixed parallax at 100 yards and yet the only time it gets fuzzy is about 25 yards and in but still clear enough for a kill shot. As long as your eye is centered in the scope every time with the proper cheek weld you can throw Parallax out the window. The marketing and falsified information is out of control.

As to zeroing - anything more than a one shot zero, followed by a confirmation shot or two, is a waste of time and good quality ammo!

What works for me might not work for you but I think you would have to agree quality equipment & its earned reputation plays a major role.

i have never seen a 1/10 moa scope. Care to share a source of one? I can be educated.

Size of a walnut at 150 yards? Wow. MOA. Skill obviously up to snuff. What is your equipment?
