What to do. Bullet moving to the right.

[ernhrtus]

CVA Cascade 40 rounds through the gun.
6.5 Creedmore 22" barrel
Burris XTR II 5 - 25x50 torqued to spec with Burris XTR tactical rings
All brand new

Hornady Amercan Whitetail 129g
100 yards

First round of 5 was at center
Second group was at the top ring above the 7

Shot the first group with about 15 seconds between each shot and first 3 were far left then the next 2 were in on the 9.

Waited 20 minutes
Second group was shot a bit quicker, maybe 10 seconds, and with a couple clicks to the right.

My concern is the movement from left to right. Both groups moved a couple inches after what is considered a cold shot.

New to longer distance rifle shooting and wondering what I need to focus on for this to go away?

Suspect scope not mounted tight or turrets are kaput.

Assuming scope is not the problem (big assumption) I would use hornady 140 gr. ELD before looking at anything else.

 

[oremike]

It is not that unusual for the first shot out of a cold clean barrel to have a point of impact different than the rest. In some shoots they allow a fouling shot for this reason.

Maybe check the stock/barrel for tight spots by looping a dollar bill around the barrel and checking for contact after each shot
Have someone else shoot it and see how they do
Shoot on a different day, it might have been environmental conditions like wind or mirage or something
How are you shooting it? Using a sling, of bags or a rest, off a bench or the ground?

Bipod with bag under grip area.

I'll check the dollar bill thing and do research on what effect it has if it does touch..

Make sure the action screws are torqued to 55 In-lb.

 

[Member 53328]

When shooting make sure your reticle is crisp and clear. The target may be fuzzy and that's ok. If you focus on the target over the reticle you will start circling/walking shots.

Maybe have someone else shoot your setup and see if they have the same results.

 

[P7M13]

Please post a picture of your rifle with the scope mounted.
Have someone video you shooting.
If mechanical, your strings could be loose scope mounts, improper torque between your receiver and stock, or even a loose barrel.

Aftermarket muzzle brake with adjustable timing.
Did you install, and what was your torque?
Examine its internals for bullet shedd/scrapings.

Might be a big part of the issue. One of them was just past "tight". Used the fat wrench to torque them down.

Thank you.

Timed. Nut tighted to about 25 ft./lbs. Had to use a torque wrench combo to get it close.

Looks like I need to go shooting again. The front action screw was not tighted to any real spec. Barely hand tight.

 

[P7M13]

Torque on action screws is critical. All two or three need to match manufacturer specs.
Does the stock have pillar or a frame bedding? You might want to bed it since you're going to be messing with the action screws.

Am not sure. Have not had it apart yet. Will after next weekend though.

That's a fair amount of vertical movement for scoped shooting at 100 yards. It would be one thing if the stringing was just horizontal...

Loosening from a muzzle device can easily cause vertical variations like that, as the shifting gasses change POI.
Loose scopes, in my experience, have no consistency from shot to shot, and you wouldn't even see horizontal stringing.
If your rail mount is loosened but still relatively tight, you might see horizontal stringing like that.

 

[DirectDrive]

1) Don't use a close range pistol target for this.
Get some "Redfield" targets.

2) Verify that your action is properly torqued.
3) Verify that your barrel is free-floating.
4) There is a thing called "heat-walking"
POI will change when shots are fired with little or no cooling time between shots
