I have a 7mmstw barrel for my tcr mag rifle went out and shot it for the first time today..Well shot it four times each time the primer was pressed flat and a hole blown through and open into the firing pin hole ..Had to bang on the gun to get it open..Now if it was a hand load I would say too hot. but it was a factory round..
Is this common with stw like rounds?
Also this barrel was a rechamberd 7mm mag but there is not no markings on it who did the rechamber job Could this problem be a fault in the workmanship?
