I shot this group today.
7mm-08
120 gr NBT
50.0 gr Ramshot Big Game
CCI 200 primers
Remington brass
Loaded 0.015" off the lands.
100 yards



The fifth shot was from a bit of a warm barrel, but as you can see I'm stumped as to why I'm getting shots touching close to 2 inches apart.

A previous 3 shot group has the same pattern, with two shots touching and a third 0.53" out.

What should I try to tighten the group?

Scope good?

I would shoot a few more groups with different charges and powders to see if you get a better result. I had a similar experience with one of my rifles and I could not find a powder or a charge that would work. In the end, I switched bullets to a different brand and the problem went away. It could be that your barrel doesn't like that particular bullet.

What kind of rifle?bedded? scope? good rest? details...

how good was your rest? if you don't have a consistent rest you'll string them like that. use a bag under the buttstock also.

Barrel freedloated? Keep the info coming.

Good rest. Sandbags fore and aft.
Scope - Minox ZA3, Talley lightweight mounts. All screws tight.
Rifle: Weatherby Ultra Lightweight.
Not bedded.
Ultra Lightweights are supposed to like a little upward pressure on the barrel.
Not freefloated.
Fired at 6X.

What bothers me is the consistency of the inconsistency. If the scope or mounts were bad I would expect more variance.

Here's the 3 shot group I fired before the 5 shot group. This group measures 0.93" center to center. After I fired this group I let the barrel cool then adjusted the scope 10 clicks up and 3 clicks left.

Something you'll hear over and over again about "2 in, 1 out" type groups is to try seating in a little deeper. Lots of guys have seen groups shrink and become nice tight little triangles or clusters with that method.

Base screws that are tight don't mean the bases are tight, Bases should be installed 1 screw at a time to make sure the bases are being held tight by both screws!

I'm trying to visualize what you mean and it just isn't happening.
