Thread: Split shoulders

To have any hope of a Diagnosis ' more information is needed . Rifle / age /actual load . for a case to fail what happens is that it is forced to work beyond its acceptable limit . This can be a brass or even rifle problem , but the answer will be found by measuring the rifle ( not as easy as it sounds ) or by measuring the brass pre and post firing .
Giving the Rifle a real good clean ( chamber area ) is a good start and then measure cases including thickness of the brass . I had a split case problem with a FR8 , I solved it by using Milsurp brass because it is thicker . And PLEASE do not buy into the ridiculous practice of annealing things with candles ,that is the preserve of monkeys .
