Is it just me.... or....

Check your eye relief to the scope. Too far or too close can do that. Don't ask how I know. Could also be inconsistent cheek weld and body position.

I am going to put $2 on inconsistent mounting of the human to the rifle.

I wish that were true... that would be a really easy and "cheap" fix, lol!

What kind of optic are you running? Base and rings? Ever box test your scope, or run different distances by dialing and return to zero and shoot your zero and still be on?

In the past I've shot out to 1K yards and then straight back down to a 100 yards to see if it shifted... and it was fine, but this was months ago.

Search SH for the threads on fixing the wobble with the AAC mounts , the can not going back to the same spot every time will give zero shifts . Are you pulling the can in between sessions ? If so leave the can on and see what happens .

I pull the can off every time I store the rifle... if this is what you're asking.
I gone and tried the AAC mount fix... it's on their solid and is hard as hell to remove cause of all the carbon build up on the muzzle device, but it almost feels like the more I put the can on it's starting to get looser. I just emailed AAC to see if they can just convert my can into a direct thread on... this QD ratchet sh*t is already annoying me.

I've been taught the ways of the parallax

My POA and POI are pretty consistent with the 3 to 5 shot groups I take.
This is probably the rare times someone can say the rifle was shooting crooked

I'm gonna guess its the can and/or scope base loose. I had a similar issue once, but no can and the base was loose, I really couldn't feel it until I checked the screws.

[islandermyk]

I'd get out the ear plugs and see if it changes on either a long string or from one time to the next running it without the can just to eliminate that possibility

I may have to try this out... I hate shooting without a can

Leave the can mounted up next time and see if the zero shifts . Also you want to catch the same thread on the muzzle adaptor every time so it indexes in the same spot every time .

I will tear my rifle apart tomorrow... and will update on this.

You guys are awesome! Thanks for all the help... really appreciate it!

I'll go through it tomorrow... I think I have enough "Red" loctite in the tool box

The can indexes the same spot every time... I think that's the way it was designed. It just bothers me that I have to always worry about rezoreing the rifle every time I pull off the can... what a pain...

If you ain't sleepin' with it, how do you know someone is not "adjusting" it for you...just sayin' you might be chasing a bad joke on you...
