Just started working on shooting off hand and off barricades in preparation for shooting my first PRS match in March. I am a experienced shooting and have all the fundamentals down. After I confirmed my zero I started shooting off a barricade using a sling and pump pillow. After running 35 rounds through the gun I noticed a very consistent POA and POI difference. I was holding center on target but was hitting 2" low and 2" right aprox At 200 yards.
Do any TR or off hand shooters have any idea what would be causing this? Would like to fix this habit quickly before it becomes ingrained.
I am shooting a savage action in a MDT HS3 stock with a MDT skeleton butt stock, chambered in 260ai. The gun has a muzzle brake and has been balance to just in front of the mag.
If you need any more info to figure this out let know.
Thanks

Is your barrel touch barricade or are you canting rifle or your trigger pull is not straight back something to think about at 200 yards
And further out does not take much could be your breathing even
 
Could be body positioning. I find that if the angle between a line through both shoulders and the rifle is less then around 90, I'll throw the shot to the right. When prone, it is easy to keep 90 deg, but pretty much any other position will shrink the angle.

Barrel is not touching. This much POI shift would not be from canting. Think I will have some one watch/ video me next time I am shooting.

Are you shooting right side? Where is the sling attached on the fore end? Hitting right and low with a right sided shooter could happen if the sling is attached on the right side of the fore stock, rolling the rifle over and down when it fires if you are slung up hard.

What position did you have the support when initially zeroed? If prone( or any position) was the sandbag, back pack, bipod, whatever under the front most part of the forearm?

That looks like a pistol diagnostic diag.

Rifle is slung up on the bottom of the fore end and on the left of the butt stock. I am shooting right handed.
 
I assume you shoot right handed.

As mentioned by others, cheek weld, parallax, scope shadow are a few reasons but sounds like you are on top of those and they are obvious to an experienced shooter.

Usually a .308 or up will have just enough recoil to highlight fundamental issues like positioning however a .260 isn't a .308 but you may consider it anyway since it is a new rifle to you.

What about left hand position or right elbow position. With a good PR and zero, low and right is somewhat of a classic position error with left support hand or right elbow slippage/position.

My guess, LOP, position and eye position relative to eye piece.

Consider this test... set up target at distance, shoot center in your favorite position (prone?)... adjust scope if needed. Be aware of how the rifle is positioned against you body vs grip, head, eye, etc.

if the buttstock is away from your cheek, that is a big problem.. common one too.

Once confirmed move to barricade test and keep same contact with rifle. With proper trigger and follow through, the POA and POI should not change from prone.

If it does and the error is repeatable, the change in body position vs the rifle is causing the issue.

You may need to favor the rifle set up for the "worst" position to get POI and POA to match and just adjust for the "best"... or have a stock that can adjust with you quickly.
