    Years ago , I looked into the Blaser R93 , as they had a what I thought was a nice rifle , I did some research , and simply was not happy with what 2 oversea's gunsmiths had to say , at about the same time , they had a spate of blow ups ( now all makers can & will have blow ups , just the nature of selling firearms , you cannot stop stupid acts , or negilanace , or hot or incorrect ammo/reloads being used ) .
    And where other makers rifles fail , the action usually holds together and at the very leasts stops the bolt coming back into the shooters face .
    When I looked at the blowups that caused the bolt to fly back into the shooters face , it seemed that the calibres where a couple of belted 300 magnums and a rimless as well , they where the hunting versions , and they failure seemed to happen , when you had a hot load that caused the primer to fail/pierce then the hot gasses vent down the firing pin hole , and then the gasses destroy the plastic washer used to cam & lock the finger splines into the locking groove , then the action is unlocked during firing .

    At the time , the rumour was that the different R93 338LM actioned rifle , had a metal washer to stop this happening in a 338LM rifle .

    I choose to buy & use other rifles , thats just me ,

    Later Chris
