    Resistance for cocking....

    Resistance for cocking....


    CYA friends:


    All actions, rimfire or centerfire, have to have a method for the cocking piece to have resistance for it to cock, as the bolt handle is lifted.


    As the cocking piece rides up the cocking ramp, as the bolt handle is lifted, something has to give resistance to this cocking effort.



    In the Turbo action, for example, the resistance for cocking is in the form of the cocking teat being resisted by the clearance slot in the bottom of the tang of the action.


    But, there's a RFBR action on the market, that is designed to restrain its threaded bolt shroud, so the resistance for cocking is taken up, not by the clearance slot in the bottom of the tang, like the Turbo, but by the cocking piece bearing against the slot in the bottom of the shroud.

    Resistance for cocking


    CYA friends:


    In a contemporary RFBR action, like the Turbo, or the Swindlehurst or 40-X, or my XP pistols, the resistance for cocking comes from the cocking piece bearing against the clearance slot in the bottom of the tang....


    As you lift the bolt handle, this resistance to cocking allows the cocking teat to ride up the cocking ramp of the breech bolt...(locking lug collar of the Turbo.)


    So in this contemporary example, we have one degree of wear characteristics.




    But.................



    What if the resistance to cocking was the cocking piece bearing against the clearance slot in the bolt shroud, itself?



    Then what kind of wear characteristics will we have?
