Cold bore shot always off 1" or more

My CZ 452 .22 LR American almost always shoot at least 1" off and I never know where from shot to shot. After 1 or sometimes 2 shots it will go back to grouping where I last left it sighted in averaging 1/2".

I've had at least 8 centerfire bolt actions and they might be 1/4" off but not this much.

I've got a Leupold 3.5x10x40 that came back from the factory for tracking problems and seems ok now.

Makes it tough trying to head shoot that first squirrel or practice tactical shooting.

Getting different rings and base, so I hope that helps.
 
Is that a cold barrel or a cold, cleaned barrel?

Not that it matters. As I recall, if you hold a rimfire with the muzzle an inch or two off the ground (with maybe a couple of folds of cloth to stop dirt blowback), you can shoot to your heart's content without making more than a ffsst sound. Then, when you're ready, you can bust that tree rat.
 
The barrel hasn't been cleaned in over 4000 rounds. I use sandbags and a solid table for checking at 50 yards.
 
sounds like a cold barrel problem to me which effects all rimfires. I always shoot at least 5 fouler shots to get the barrel back to close to what it was then I shot an additional 5 sighters before i start shooting for record.
This has matter with any of my rimfires which are an Annie 1903, Annie 2013, Remington 40x or H&R M12.

In a tactical .22 match, I wonder if that would be legal. I hate to waste ammo anyhow. It wouldn't be so bad if it was consistant but it isn't.
 
My Rem 504T puts the first shot from a cold clean bore at 10 o'clock and about .750 off of POA. Second shot is half that, and the third shot will be in the X if I do my part. I only shoot this gun at paper so it's not a problem, but I can certainly see your delima if you can't predict where that first shot will go while hunting. A couple of things you might try: (1) Bed the action and make sure the barrel is floated, or/and (2) play with torque values on your action screws. The very first thing I would do is check to see that the barrel isn't touching the stock somewhere along the barrel channel.

Might help, might not.....but sure won't hurt. :)

Good luck with it!

cold shots

Cold shots always seem to be a problem!! With my 22 lr target rifles, the first shot is ALWAYS at the 10 o'clock about a 1/2 inch off the X at 50 yards. By the third or fourth shot it's dead center. If you are hunting deer at 100-150 yards and your experience has been that a cold shot hits high and to the left, you may just need to compensate for this result. If you can determine the amount of cold shot point of impact in relationship to your point of aim at a given distance it may help solve your problem, but you're going to be in the ballpark. When I set my hunting rifles up, I try to test fire them in the conditions that I will be hunting - more or less. A two inch MOA difference at 100 yards on a good size animal isn't that bad - all things considered.
 
It makes the first shot squirrel hunting a problem. Whe I first got it I couldn't believe I missed a few squirrels. Now I know why. Same problem with tactical .22 shooting unless you can shoot it before the match. We don't have any around here yet anyhow.

The channel is all free floated but it has pressure at the tip on the 452 American.

I am wondering if the barrel would just pull down into the tip if I tried to remove it.

Had a B&C synthetic stock for a R77 and that is what happened with it.

I haven't glass bedded it yet.

Torqueing the screws crossed my mind, but I don't have a torque wrench yet.

I shot a 5 shot group at 200 yards and they strung out vertically about 3" with one 3/4" to right of bottom shot. . I'm thinking that could be caused by the tip pressure, but I'm not sure.

Later.
