Bolt head with relationship to headspace

[Zero333]

I've swapped bolt heads from different short actions and headspace was still good within spec. Headspace will not be affected enough (or any) to matter when you flip the head.

I wouldn't be advising anyone to ever do this. Have you ever measured the differences between the bolt face and rear of bolt locking lugs? Or trued the receiver lug abutments? Just because it works in one rifle and another does not mean that every rifle can just have bolt heads swapped without consequence. This is shady and shoddy advice at best.

I agree with you.
I've seen a .010 difference in headspace that wasn't caught that stretched brass and got premature case separations.

Today I flipped 3 bolt heads and headspace didn't change enough for the go & no-go gauges to do their jobs.

If the OP can't get the proper go-no-go gauges he can use the Hornady modified OAL cases, with a layer of masking tape on the head they turn into no-go gauge.
I've measured 5 different hornady OAL modified cases and they all measure EXACTLY the same as their corresponding go-gauges.

I wasn't trying to impune your character or the fact that you can and did succsussfully flip a bolt head, or swap bolt heads without issue. Swapping bolt heads is more risky than simply flipping one 180 degrees, but to give that advice isn't something I would do. You have to realize that there are people reading this that have basic skill sets and might not understand what the consequences might end up being. Just trying to subvert a possible catastrophe from a less knowledgeable person. Not everyone has a set of go nogo gauges or a OAL case.

Cheers

I agree with you. I should of worded things more carefully.
