No.4 Mk1 headspace issue

[Plinker]

I have a Longbranch No.4 Mk1 (FTR) that swallows the "Field" headspace guage. The barrel is in fair-plus condition, so I'd prefer not to rebarrel at this point, but I will if there's no option. Can I get away with swapping in another bolt-head? It's currently fitted with a #1 head.

Thanks in advance for all recommendations.

That's the ticket, new bolt head.

Yup, a #2 or #3 bolt head will do the trick, but you'll need the go and no go gauges to ensure you have the right one.....

Thanks - I have a full set of guages, so no problem there. I'll order a #2 and a #3 head.
