CZ 455 22LR/22Mag one barrel is way off, how much is too much?

[problemchild]

When I switch from one barrel to the other I have to dial my scope way the hell to one side. I mean it takes 55 clicks left or right and 30 clicks down or up depending on which barrel it is.

Seems someone didnt do a decent job facing one or both of the barrels. Should I call the factory for the 3rd repair in 3 months or let it go. Its a real PITA to get the scope back sighted in every time.

That's only 16 MOA -- just over 1/4 of a degree -- out of true. Annoying, yes, but doesn't seem unreasonably out of tolerance.

You may find you can improve it a bit by carefully seating the barrel or paying more attention to torque settings on the set screws. Or it may improve as it wears in. (Or maybe not.)

I don't think that's right.I have 3 barrels(17HMR,22LR,22WMR).Windage is only a couple clicks different on any of them.Elevation is further off,but I accept that as being due to differing trajectories.

I would contact CZ.Be interested in their reply.

That's way out of tolerance in my opinion. Assuming the scope adjustment is 1/4" per click at 100yds, 55 clicks of windage to get on target is a hair over 14" of windage error between the two barrels @ 100yds. Heck you are probably using way more than half of the scope's windage adjustment just to compensate for the error between the two barrels. Time to let CZ solve this issue.

As an aside if you happened to purchase the rifle thru Davidson's or Gallery of Guns they have a lifetime replacement warranty on every firearm. Might want to check and see who the distributor was. Good luck.

Not does not sound acceptable to be, I'd pack that rifle up and ship it right back ASAP.

Called the warranty center. They want me to send in the "bad" barrel and they will replace it. Is there a way to find out which barrel is the offending barrel without going to the range yet again?

Only thing I can think of is this.

Mount the scope and set it to its optical center, that is count the number of total clicks from left to right. Divide by 2 and then adjust that number of clicks to the left (make sure you start with the windage adjusted all the way to the left and don't force it. It doesn't have to be exact just close). Do the same for the elevation (except up/down). Put a piece of paper with a 1/2" circle (maybe even smaller) on it on the wall, move back as far as you can from the wall and put the rifle on a solid rest. Remove the bolt and boresight the rifle (look thru the barrel at the circle) on the circle on the paper. Look thru the scope and note where the crosshairs are in realtion to the circle (how far right/left/up/down). Change barrels and boresight on the circle (don't adjust the scope at all) then look thru the scope again. The barrel which causes the scope to be farthest away from the circle is the barrel which is bad. It is important that the scope is setup at or near its optical center and not adjusted after that.

Another way to reset to "0"


The absolute way to center a scope is to use a mirror.

Step one, place mirror in front of the objective lens and use a rubber band to hold it there

Step two, look through the scope to see two sets of reticles

Step three, move the windage and elevation screws until the two reticles are together and look as if they are one

Step four, remove the mirror and use a bore sighter to sight the rifle

You have now set the reticle back to the factory center.
