I have a bolt with a straight handle, ordinance bomb on bottom side of bolt root, SN (or NS) stamped on bottom of safety lug, single small vent hole up forward. What era rifle would it be a proper fit for?
Thank you.
Thank you.

Your bolt would be correct for a very late-1918 or 1919 Rock Island Model 1903 rifle.

Thank you very much.Comment

"...ordinance bomb"... OrdNANCE. An 'Ordinance' is a law.
You cannot just put a bolt into any rifle. Bolts require fitting for headspace by a gunsmith.Spelling and grammar count!Comment

For '03s, my understanding is that headspace is set in the chamber. Unaware of a bolt based procedure beyond swapping bolts until one gives serviceable headspace. This after initial reaming of the chamber with a particular bolt.
From the happy coincidence department: one of my shooters is a Greek return, S/N 1.37M range, so Nickle Steel receiver. Independent of this I got a 3 bolt set of bolt bodies off of eBay, with one advertised as "NB" on the bolt handle. That NS bolt ran long on two of my HN rifles, but gauged right on with that CMP NS action. So they're together now in all of their gummy glory.Last edited by togor; 11-01-2018, 04:15.Comment

In the "happy coincidence department", a late NS bolt came along with the above mentioned bolt in the deal. Out of curiosity I tried it in my 1903A1 which had a Remington bolt in it, said R bolt closed with the faintest resistance on a go-gauge, minimal headspace. The "new" NS bolt closed with the exact same resistance on the gauge. (And yes, the checks were made with just the stripped bolt bodies, no extractors.) They are now together in all their "gummy glory" also. The very best part of the story is that I got the pair of bolts for a paltry $40.
Sorry for the spelling error. My sainted Mom passed away on the day I wrote my initial post and I was trying my best to divert myself from the grief by engaging in some 'normal' gun talk.Last edited by gnoahhh; 11-19-2018, 06:30.Comment

I have 35 03A3 bolts; there is not .001" difference in the effect each has on the length of the chamber from the shoulder of the chamber to the bolt face.

I also have 2 boxes of 2 Brown and Sharp complete bolts. All 4 bolts are identical. If there was a plan to correct the length of the chamber with a bolt logic would dictate the bolts would be different.just need to headspace to make sure and try a few if yours do not work (headspace correctly)
designed that way,

if you gonna quote, quote the entire post, not take things out of perspective,
the 03 (and A3) were headspaced when barreled,
bolts designed to be swapped out, if needed, but not to need any adjustment or fitting, (just check headspace to make sure, due to manufacture tolerances etc)
unlike say in Enfield, that required the bolt head to be fitted,,
I've rebarreled, and worked on many a 1903 and 1903A3, there will be some variation in headspace when bolts are changed , likely due to wear on the receiver and barrel,Comment

I have a bolt/action chart that reminds me which bolts headspace how into which actions. Not all 03 bolts headspace the same. Given lots, maybe.Comment
