Okay I went to the range this morning, it was a little windy but what the heck. My question is as you can see from the picture that depending on where my front sandbag was the groups change quite alot. This is a stock Tikka T3 stainless in 260 rem. The load is 140 gr Berger hunting VLD in Remington brass with Federal 210M primers and 39.5 grs of H4350. Does indicate that bedding would help. And I know it's good enough for a hunting rifle, I just like to make it the best I can. Oh the scope is a 4.5-14x32 Burris timberline and range is 100 meters.

maybe you just suck at shooting a rifle, just like I do!
(I bedded all my rifles anyway)
 
Your groups are small, and you group consistently. Could be a heated barrel if you are shooting quickly, Tikka Stainless is a fairly thin barrel, meant for hunting, not target shooting. If it was warm give 10 -15 minutes between strings.

Otherwise, I think you answered your question. "...it was a little windy but what the heck." Most of your groups push right it looks like... was the wind left to right?

This I believe is correct as a heated barrel can change things quite a bit. I have a Tikka 695 deluxe in 7mm mag and I do my load development and sighting in Feb or March as the temp is low enough to cool my barrel and it is the same temp as I hunt in.

I think if you are still concerned I would have to ask if your hand was on the same part of the stock each time you shot. If the front bag was close to the action your arm/hand may be a bit far out and less comfortable than when the bag was out and your hand was in a more natural position. Just a thought.
 
Hand was in the same spot and the small groups were the last ones. All groups were 3 shots then shot the .22 for for awhile between, so definatly not heating. The only thing different was the position of the front bag, wind being somewhat steadyish.
 
I'd bet the stock was being pushed up with the bag farther out. I'd put in a larger pressure point near the swivel.
