What causes a group to string horizontal? Half inch groups that shots are touching. Gun, load, shooter or something else. Thanks again to

Horizontal dispersion can also be the load. You might be near a good load, but below it, or above it in powder charge.

.2 grains up or down for adjustment, for a 223 case. When a group strings (if it's not something else causing it), you have either just passed an accuracy node or are approaching one.

When I see horizontal stringing, the first place I look is to make sure rings and mounts are tight, then I look for a bedding/binding issue.

Half inch groups? Do you really expect much better?

Of course I agree with Chad. For a .223 case, I step in .2 gr increments.

I failed to mention tightness of all the screws on the rifle, and rings. I made an assumption everyone knows to confirm those things first. Assumptions get everyone in trouble.

Bases and rings have been torqued to accepted specs. Gun is a Savage model 12 LPV. Doc, yes I hope the gun will produce better groups, may have to get a different shooter but I think the gun is better than half inch

Better than 1/2 MOA? Maybe.

What power scope? Bags or rest? The rifle may be shooting 1 hole groups but other variables are causing the results.

I know of one that's shooting better than .5 MOA, but it took A LOT of tweaking on the loads to get there. Have you taken the trigger pull down any? I think that model has the target trigger that will go down to 8 oz.
