my buddy has an axsis chambered in 308....has about 300 rounds down the barrel....accuracy was way off and had light primer strikes......we decided to check head space inserted a go gage everything was good added 2 pieces of tape and bolt still closed added 1 more and bolt still closed ......we decided to reset headspace we trieid everything we could think of to get the barrel nut loose and no luck even heating it would not budge.....what is the secret to getting it to move.....anyway I told my buddy to send it back to savage which he did .....he got it back tody with a note : gun checked for function range tested headspace good and that was it .....so I guess all they did was shoot it and check the headspace.....no other explaniation.....we are going to the range sunday so we shall see if it shoots any better ....anyone have a similar issue thanks
