Gunsmithing Big Horn TL3 bolt head, or bolt swap headspace?

[msbr]

Has anybody changed bolt heads (same size-same size) and checked for headspace change ......also changed complete bolt assembly to different rifles?
I know the barrel tennons/action are supposed to be tight enough spec to swap....just wondering if anybody has actually checked with swapped bolt or head. Might be nice to have a complete spare bolt assembly........
Thanks

I have confirmed head space with 3 different actions and the 223, 308, and mag bolt heads. It all spec’s. No issues.

I suspected that, since the headspace has to come from the bolt face on different rifles....thanks for the confirmation...I’m on my 1st TL3 build, and love the interchangeability.

I'm not a gunsmith, but I own two TL3's, with all the different bolt heads. I have swapped heads and bolts back and forth and share six barrels between them ...zero issues. About to buy a third one.
