please help 243wssm big problem !!!!!!!
 

I have a winchestermodel 70 super shadow in a 243wssm.Gun is only 2 years old and have never had a problem with it. approximently 65 winchester factory rounds shot threw it.Today at the range after 4 or 5 shots it started spliting the necks on the cases.Any info on what the problem is or where to start looking .

RE: please help 243wssm big problem !!!!!!!
 

when this problem started today i was using winchester factory 100 gr sp .then switched to the 95 gr ballistic tip with nickle brass and it still split about 1 out 3 cases if this helps

save the brass, send it to winchester, = get free ammo.

don't send them the loaded ammo. just the empty brass. include a note of what you experienced and the lot number off the box.

took gun to local gunsmith today and he looked it over .He didnt have the correct gauge to check it.B ut he said the way it was feeding the live round(pretty stiff) and the way the bad brass looked he said he would almost guarntte it has a head spaceing problem

RE: please help 243wssm big problem !!!!!!!
 

If not head space problem what else .I am just asking because i am lost when it comes to this kind of stuff.Most of The cases split in 2 or 3 places from almost the top of the neck to the shoulder if that helps Thanks
