I've been working up loads the last few weekends for my 7/08. I've noticed each day my cold bore shot is averaging 2.6" lower than all the other shots. The point of impact does not vary after the cold bore. I have added a new Vortex scope, Burris rings, and a Millet one piece base. Is it the scope set up or what do think I should check first? I'm confused how the scope set up can only move on one shot.
Why is my cold bore shot off?

Two things.
First to mind is barrel floating, how is it? Action Bedding?
Second, Montana Extreme makes a barrel conditioning oil that really does work to keep first shots on with all others. This is usually used with the cleaning process though.
Check your float and bedding.

I would say its a bedding issue. Sounds like the barrel is touching. Not 100% sure but it may be worth looking at

What's the gun ?

Two loads were for the 145 Speer BT and 1 for a 162 grain A-Max. Once I shoot the cold bore it shoots right on the money. It hasn't always been that way. Could the first shot be taking up slack in the rings/base set up?

I have it on a Boyd's Thumbhole laminate. It's floated all the way . The action is not bedded.

It is most likely not your scope or rings, or your bases.
Some barrels will do this regardless. Most hunters know to shoot groups on a cold barrel cuz that is what happens in the field.
Heck, even bench guys take fouling shots to settle everything in.
You might try some Wipeout products and get that barrel clean. Then see how it reacts. Cleaning every 50 or more shots could be a problem with carbon or copper build up.
I love shooting at things in the dark.
Have you checked the torque on those action screws?

Something had to have come loose, check everything. Give it a good cleaning and try again

Had a custom 22 do this. I chased the problem all over. Can't remember what it was though.

I used Wipeout the 2nd cleaning ago the I followed up with a bore paste last time. I'll check the action screws . I can't deal with the difference in shots. If I can't fix it I will have to get another barrel. Real shame too- its a good little shooter for any bullet weight you want to shoot .

I had a 22-250 do that same thing to me and it was the action screws, but I wasn't smart enough to figure it out right away, then it started doing some weird stuff, so now that's the first thing I check.

Uh..... Proly action screw at front of trigger guard. It was real loose. I swear I checked those when I scoped it . I'm an idiot!!!

Well I tighten the action screw and it just swapped the cold bore from 2 .6 high to 2" lower than the following 3 shots. I know the barrel is real temp sensitive too . Do you guys think bedding the action will make a difference?
