Are you reloading or shooting factory?. If you think you have excessive head space using a .136 bolt with the brass you are using and have the tools to measure the new brass and compare to the fired brass, you may be able to bump the shoulder and use a .125 (7.62x39) bolt.
I'm using a .125 bolt in a .136 chamber with new lapua brass and it works just fine.
All chambers are different, it's the users responsibility to check and know how to measure head space.
