I have a new 455 Lux and I've just now noticed that I can open the action and lower the bolt on an open action with the bolt handle making contact with the stock. Is this normal? Do all 455's do this?

Any input appreciated

Torque it to 15 in/lbs first. Close the breech bolt and use a feeler gauge/business card, or pieces of paper to see what kind of clearance you have under the bolt to the stock....keep track of this measurement for future reference. The bolt and stock should never be touching when the bolt is closed.

If you got room to torque it more you can go up to about 25-28 in/lbs in most cases where you won't end up permanently sinking the action...laminate stocks can take a bit more than the walnut. Most people find that somewhere in the 18-25 in/lb range is enough to keep the action put, not overly stress it, and get good consistency on their shooting.

The bolt handle can be turned down towards the stock when the action is open and bolt is to the rear, that is the problem.

Any other bolt action I have ever used the bolt handle is locked in the open position and can only be closed when the action is closed.

Thanks

Yes you can move the bolt reward all the way and rotate the bolt to the closed position. On any of my 455's that is common but they all have clearance between the lowered bolt and the stock when pushed fully down. You will also notice when this done that the firing pin has now put in the fired position.
To duplicate this remove your bolt and twist it to the relaxed striker position.You will then understand how the bolt comes apart as this is the position to put the bolt in before dismissively.I hope this helps you out.

Yes it is normal. Without the lug on the handle like the 452 it will happen. I have also done this with a savage bmag and had a hard time getting the handle back up it was stiff and the bolt was flopping around in the action.
 
Good time to research the dismantling of your bolt for cleaning.
There is a you tube version of Rimfire Central in the top "sticky" section.
Once you have turned the body of the bolt you should not be able to insert the bolt to re-#### your rifle.

Pictures of your problem would help.

Problem apparently isn't a problem and inherent to the 455, bolt handle can be turned down towards stock with the action open and bolt all the way to the rear.
 
I have to agree with hesko ''Wouldn't say its a design flaw, more like save a nickle flaw...'' from rfc.
I had to go to the safe and see if my 455 does this..well had to see for myself what the OP was referring to .
I can see this being an issue if and when I short stroke the bolt.
Pulled the 452 out as well and found out the differences .
Wasnt overly concerned, but then again time will tell the tale.

Mine did it too, the bolt opens further to clear the 22lr plastic insert for when you want to put a 22 mag or 17hmr barrel on it. It is annoying though when you are trying to cycle the bolt fast and don't have your thumb angled right.

If you removed the bolt from the rifle you could accomplish the same thing as if you were going to dismantle the bolt; holding the bolt body turn the bolt down in the same manner as if cocking.
I never tried it until you claimed it is a problem but could picture you were disengaging the cocking mechanism while the bolt was in the rifle. The bolt is now locked into the action.

How many other rifles have such a fabulous feature in order to disassemble the bolt? It lends itself to easy and periodical cleaning? How many bolts have never been cleaned? IMO there are a number of CZ bolts that have never seen the light of day. At least once a month someone complains about their CZ and did not know there is a procedure to take it apart. In the last two months my 2 CZ455's were disassembled probably 50 times while reshaping the firing pin. I am not going to try taking it apart in the dark!!!
 
Bolt disassembly is an easy feature with the 452 and 455. Easily done with a small tool that beats using a spent shell. I do mine on a regular basis as well when polishing the bottom of the striker.
