I will cross bolt any rifle I own above .338. Better to have the stock remain in once piece than (may) have to have it replaced.

I have two cross bolts in my lightweight 9.3x62 and the last place I want it to split is whilst on an expensive Hunt in Africa or the Northern Teritory.

I have ordered a 458WM and it will be cross bolted as well. I think of it like travel insurance, handy when you need it.
