savage 110 338 lapua grouping

[updogcharmer]

Have what seems to be a strange issue with my new gun, been shooting a couple weeks now and seems like the grouping moves by itself and then back again.
Anyway I shoot three shot groups and two would be spot on then the third would be as far as three inches away and could be anywhere.
I am currently only shooting at 200 yards, would like to move out but not until I can have some better consistency.
I am shooting off a bypod and bags FYI
Loads are berger 300 grn hybrids, 91.5 grns h 1000
thanks

first, welcome to recoil !
Get rid of the bipods until your sure of the gun/load/group
check ALL the "nuts and bolts" on the weapon.

I have checked the nuts and bolts and have shot some just on bags, also with some earlier loads had a bit of copper fouling but cleaned up nice.
my intention is to should it in the sled a little and see if anything changes

How fast are you shooting and how much is your 3 round moving?

[updogcharmer]

shooting 3 shots in maybe 5 minutes and then check and or wait 5 minutes or so.
Groups can change up to thre inches or so but also has some real inconsistency as well.
last time out I had 2 friends and we each took a turn shooting and that didnt even effect the results
