POI Change, Ultralight .308

hi
i have recieved a great deal of uselfull advice on my mk1 77rl from this sight, i have finally found a load it shoots well with, getting 20-30mm groups at 100 yards for three shots, the only problem i have now is that while sighting in the groups always seem to land in a different place, but still tight groups, like one group will be 3 inches high, and 2 inches left, but after adjusting it the bullets will land for sxample 2 inches low, and 3 inches right! it is getting very frustrating so any advice you guys have for a young hunter would be helpfull, ive been hunting for 8 years but only turned 20 this year. what could be possibly causing this? and what could i do to sure it? freefloating? i have a leupold vxIII 2.5-8x36 on it so i don't imagine it will be the scope, any help would be appreciated as i have a deer hunt coming up next week and need to get it under control
thanks in advance,

Gary

are you contradicting yourself?   and to you possibly misunderstand the way that the adjustments work on the scope?   

"after adjusting it" the bullets should fly somewhere else.   it's just that your scope May not have the fine adjustment capability that it is labelled for.   SO......do smaller increments of adjusting the reticles when trying to change the point of impact.

i would also consider 'pressure-bedding' the front of the stock against the rifle barrel.    don't kid yourself about free-floating being the answer to all of a rifle's bedding problems.   Remington pressure-beds many of their sporters.......and gets Top Notch results.   i've worked with them and see what that simple trick is worth.   

that's all i can think of for now.

i have had the same scope on my zastava .223 and have had no problems with it even going thru the shoot a group, then 16 clicks up,fire another group, 16 clicks right etc until back to origanal poi with no problems and yes, i do understand which way the turrets will move the reticle. the groups will be in a different place even without adjusting it, like il fire a group which may be 3 shots into 30-40mm at 100 yards, then let the rifle cool for 15 minutes or so and fire another, only to have the group land in a different place entirely sometimes as much as 4-5 inches away.

The Ruger 77's are bedded with a pressure pad in the forearm.  You might try first working with the action screws.  The fron angled one is to be tightened first and you want to tighten this right down.  Next tighten the rear one but not as tight as the front.  Last you just want to tighten the center screw so it won't fall out.  If this doesn't help I would take the rifle to a good gunsmith and have the action bedded and the barrel free floated.  I have two 77's and I have them both setup this way and I get excellent accuracy from both.

I have a few 77 UL's as well.  Have them glass bedded and put in timney trigger.
