Thread: stiff bolt after firing Steyr Mannlicher

    stiff bolt after firing Steyr Mannlicher

    Some insight very much appreciated...

    I have an oldish (early 1980s) Steyr Mannlicher 'L' in .308.

    It shoots well, but the bolt is exceptionally stiff to open after firing a shot. It cycles very smoothly when dry firing, but as soon as you take a shot, you have really force it to get it open. Oddly, the first shot in a group is the worst, with the second and third being easier (though still not at all easy).

    Does anyone know what might be causing this and what the solution is?

    Is that with factory or home loaded ammo??

    Bog standard Federal 150gr factory ammo.

    what do the cases look like?
    if you dry fire (no case) how does the bolt lift effort compare?

    Any chance there is oil in the chamber on that first shot?~Muir

    Thanks for the replies.

    Bolt lift when dry firing is easy - not as smooth as my T3, but perfectly smooth enough.

    Cases look normal after firing.

    Oil might have got in, but I'd would have thought it would have burned off after the first few shots, and the problem persisted throughout a 30 shot range session (firing groups of 3 with 5 min gap between groups, first shot in each group always the worst).

    whats it like with other ammo say sako or geco! or your home load's, thay may just be hot loads and your steyr don't like them ? can also be as a result of dents or pitting and the case fireforms into the low spots thus grabbing the walls if you get what i'am saying prob wrong but haho can see the chamber or rifle from here LOL .one of my AR15 m4's hated mil spec ss109 rounds and only would eject home loads due to tight chamber all the others would eat milspec ammo all day long,so i had it polished and that sorted it out.

    I would think you have pressure problems !
    Have you run them over a crono to see what there running at , then you could compare them to other factory ammo .
    Then you could mail Federal and check with them . Ive had to beat rifle bolts open when guy's have used loads for there old rifle's that have not worked in there new rifle , but as you say these are factory loads and the bolt is closing correctly but very hard to lift the bolt and the rounds are not grouping so I would say a bad batch of ammo .

    Have a really, really good look at the brass mate. Is it smooth or are there dimples / bumps.. especially towards the neck end? I missed the early signs of throat chamber damage and it proved terminal for the rifle.

    take the bolt apart, check the firing pin is in good order, check the extractor is not bent or dirty. Clean the bolt face properly as well as the recoil lugs. give the chamber a good clean with acetone on a brush, give the recoil lug recess a really good clean with a 12g brush too.

    you may wish to check headspacing too of course, but I bet it's a cleaning issue.
