    I have a CZ 527 Bolt Action 223 rifle with a Votex Venom Scope.

    I shoot everyday.

    200 yards is killing me. No matter what I do something always seems to go wrong. For instance on Tuesday I was shooting great. On Wednesday I went out and couldn't even hit the target. I had to bring the rifle to 50 yards and bore sight it again.

    Today, I'm shooting great. I go to help my friend dial in his rifle. I go back to shooting 20 minutes later and I'm 6" high and 4" left. I took five shots with the same results.

    How the hell is this possible. Conditions outside were perfect.

    The inconsistency of the scope not holding its trajectory is driving me nuts.

    I'll watch a hundred videos, read a hundred books. I need to solve this problem.

    Thanks all.

    Check to make sure all of the mounting screws are tight, and the scope is properly mounted. Could be a bad scope, it happens.

    I fought a bad scope for 3 months.

    As jmr40 suggested, check the mechanical basics first, if good, swap to a known good scope.

    Please report back.

    If all the scope mount and ring screws are tight then most likely the scope needs to be sent back for warranty

    What happens when you are given a different rifle, or you give your rifle to a different shooter?

    Not "rocket science" just a simple experiment....change out the scope!

    In addition to checking scope mounts check to see that the rifle is properly seated in the stock and the action screws are tight. It is possible to get the magazine box installed a little off on some rifles and it puts pressure on the action.

    Make sure your barrel is free floated. I had a rem 223 that would shoot groups to poa then suddenly shift several inchess at 100 yrds. found a small dimple on the end of the foram touching the barrel. I filed off the spot and it still shoots poa poi today.

    I am with varminterror. Have someone else shoot the rifle along with you shooting a different rifle.

    Check your rifle to to make sure everything is tight and properly torqued. This includes the action screws, scope mount screws, ring mount screws and ring cap screws. I can't stress enough to use some type of torque wrench. You do want everything torqued properly. Not enough torque and things can come loose and too much torque can mess a scope up.

    Also check the barrel channel on the stock. Some rifles like to have a free floated barrel wheel others like a little pressure.

    If all that checks out, then you know it is the scope and it needs sent back. Every manufacturer can send out a lemon now and then.

    What kind of scope rings are you using?

    I had it professionally installed. All the levels, vices, torque wrenches.

    swap out the scope, easiest thing to check.

    I recently sent a Vortex PST back to be evaluated as I was having some dialing issues. They said that they found nothing wrong, and asked me what type of rings that I was using. They are Leupold QRW rings, which was fine. They were worried that I was using the kind of rings that clamp from the sides. From what I have been reading on the internet, this can cause issues with certain scopes.

    The scope has been returned and I am waiting for a nice day to go test it.

    I would do just what wbm said to change out the scope. If that doesn't fix the problem it's probably the barrel heat warping. I have one rifle that does that. I finally got it to hit dead center first shot but if I keep shooting it will keep moving the point of impact to the right. It's not so bad in the winter but during the heat of summer it can go as much as 10" over at 100yds.

    Scope mount would be definite first thing to check. There are a lot of variables. If you could post a couple of close up pictures might help a lot.

    Before you condemn a scope or modify the gun, start with the mount first. What type of mount was used? Is it one piece, rail, separate bases with rings? What type of rings are being used? At times very odd things can happen like weaver/picatinny not getting along, small slop in the slots can allow it to slide fraction of an inch while still feeling torqued. Bases might be shifting, scope could slide in the rings, the rings may not be in the correct position on the scope body (ie part of the bell in the ring), rings could be slightly different heights leading to tube twisting, etc. Bases themselves could be loose but appear solid while the rings are tight. The list goes on...

    Everyone has given you the usual blah, blah, blah stuff and I concur with the blah, blah, blah - check the obvious scope secured, barreled action secured, etc. - eliminate the obvious to ultimately answer your question.

    Pretty much that at this point.

    Youve got your suggestions and methods of testing, let us know what you find.

    Something to remember also though, is just because you had something done professionally, doesn't mean that the person doing it didn't make a mistake.
    I've seen plenty of professionals screw up, it's human nature.

    It might well be a defective scope. I would say that is the most likely root cause. In any event, you'll have to take the scope off. Before you do, make a little pencil mark on the scope to show where the halves of the rings meet. That way, you can put the scope back in correctly without levels and such.

    Once it is off, remove the scope base. If the finish on the receiver is scuffed, you likely have a very subtle problem where the front base screw bottomed out on the barrel threads before the base was fully tight. Grinding a little off the end of the base screw will fix that. Chased exactly that problem for a while once upon a time.

    Since it works sometimes I would suspect the scope. Although the other details should be checked.

    That doesn’t mean much to a fella with a scope problem, retrace your steps and examine carefully each connection and don’t over torque the scope tubes.

    Mr. WICK: If your vision allows it, does the rifle still have (decent) iron sights, which you could check at 50, then 100 yards?

    At least you would know whether the Basic Rifle (if sights are well-assembled at the factory) shoots to the left, while using a small orange spot as a bullseye.

    The key to this mysterious situation is when he had to start over at 50 yards. A loose scope won't jump ship like that. Bad bedding or barrel to receiver threads won't jump that much. Shotgun pattern or two or three here and there is way different than starting over at 50 to get on target.
    Scope has loose internals.

    Could possibly be a mount screw that's too long and touching bolt head.
