I also posted this message on a Krag forum so it might be familiar.
I'm a new member with a question about headspace issues with Krags. I'm not a gunsmith by any stretch of the imagination and this is the first rifle I've ever had a need or interest in testing its headspace; so be patient.
I have a model 1898 with a serial number in the 436,xxx range that I inherited from my father. Family members have told me that my father had replaced the barrel on the rifle but didn't have the guages to check this rifle's headspace. He never shot the rifle. My father use to reload blank 30-40 cartidges for the local VFW's honor guards and would test these loads through this Krag.
Interested in shooting the rifle, I obtained Clymer Go and NO-GO guages recently to check the rifle's headspace. I understand that this rifle headspaces on the rim. I stripped the bolt and the bolt won't close on either the GO or the NO-GO guage. Having new brass that I was going to use, I was able to close the bolt on the new brass so here are my questions.
Were the clymer guages I'm using SAAMI spec and somehow not reliable or not necessary for the headspace checking I'm doing on this rifle?
I've read that some 1903 barrels require a reaming after they're installed to get them in-spec. Is this required of a Krag?
What's your thought's on loading up some mild 30-40 loads and trying them?
Anything unusual about Krags and checking their headspace that I'm missing.
Your help is appreciated.
