    I have new rifle it has Savage right bolt left port. Bolt is very stiff on close and open. With brass in it I have to apply even more pressure to get it close or open up. Here are few images of FL sized brass which I cycled and view on front of the action.

    What's the probable cause of this?

    The top picture seems to show that there is something in the chamber on the shoulder....if this is a new barrel it may be a chip from machining. If it was not fired then you may be able to clean it out...if it was fired it may be partially welded to the chamber due to pressure and you may need a chamber reamer.

    Kinda looks like you have some contact on the breach face, did it show on the bolt face? The first barrel I chambered I get it a little to tight and it would get stiff if I got so much as a little stuff on it from cleaning, a piece of powder lock it up!

    If it does it with a case in it and doesent with the case removed Then it is a head space problem.

    The marks on your brass looks like tool chatter from the reamer.

    If it is hard with no brass in it then it sounds like the tenon is to long and inter-fearing with the
    bolt face or lugs.

    If this is the problem then re set the head space and this should clear up both problems.

    If you don't have a head space gauge and a barrel nut wrench you will have to go to a smith.

    the headspace gauge for 6BR, getting me confused, I see 6BR Remington from PTG, then Forster 6mm Remington which ones do I need, this supposed to be 6mm Norma BR chamber.
    After opening and closing bolt like for a 5 minutes it start to work better, but with brass it still hard to close.

    The 6mm Norma BR is slightly longer than the Rem Or the 6 ppc so It needs it's own head space
    gauge.

    If one of the other gauges were used it will not have enough head space .

    The only way you could uses the other gauges is to shim them .001 to .002 but I would not
    recomend it Unless you are a gunsmith.

    Head space gauges are cheep ($35.00) and the proper head space gauge will save lots of grief.

    Let us know what you find. That way we will all learn something.

    +1 on the headspace. I have encountered this a couple of times when headspacing Savages using a headspace gauge but trying to chamber previously fired and resized brass. Just check your headspacing.

    Yes I will order headspace gauge, there is no other way I think, other then using FL sized brass as headspace gauge and I see many people done it :D

    the issue is resolved, chamber was cut 0.004" off center, it got rechambered, bolt operates smoothly.

    I am glad to hear your problems have been solved.

    Believe it or not I have seen much worse, and have had to set back some one full rotation (1/16")
    To get the chamber to clean up.

    So you can imagine how much trouble the guys were having with there rifles.

    Have fun.

    I didn't have time to shoot it yet, probably tomorrow I'll fire few shots, maybe unexplained fliers will go away.
