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

Schmidt and Bender PM2 5-25x56
Sphur one piece mount.
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.

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[Coffee]

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 [LOL]

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.

I may have to try this out... I hate shooting without a can [blah-blah]

UnLoctited lefthanded nut behind the trigger.

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 .

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...
