Means the headspace is excessive and you should not shoot the rifle with any ammo. Likely due to the rifle being assembled out of a parts bin. Mind you, the headspace gauge brand might matter. The 7.62 x 54R uses the same gauges as the .303 Brit.
Gunparts sells Mosin M1891 bolt heads for $18.90 without an extractor. Where'd you buy the rifle? Any warrantee?

Pawn shop buy. No warranties. I have another Mosin to compare the headspace gauge. It is good. Do not plan to shoot it if or until I get the headspace sorted out. I am working with an ebayer to hopefully get one in spec. I am getting a real vernier caliper tomorrow to take some measurements. It is a good looking rifle, bore is good, good rifling, there does seem to be damage to the back of the locking lug. Must be soft as it has some metal peeling up. I think a proper bolt head will fix it.

Will the different bolt bolt from the other Mosin fit for a check? |

Metal doesn't just 'peel'. That'd be a huge issue for me too.
The issue with the Gunparts bolt head is that they don't mention any dimensions of 'em. Means you have to buy a fistful to try with a headspace gauge(you'll need a set, not just a No-Go or Field too) until you find one that is good. Just like a No. 1 Lee-Enfield. I wouldn't 'work with some guy from E-Bay' either(aside from E-Bay being rabidly anti-firearm ownership). You need a smithy who knows Mosins. Dunno how prevalent those are, anywhere, never mind Texas. Like mehavey says, excessive rim clearance cannot be solved in handloading. Needed to be bigger. snicker.

I get it. If someone knows where to get a handful of bolt heads to try I am game. Since the damage to on the bolt head, I am hopeful, Need to find out why and how it got that way. I will look around for a smith. |

I have 30+ 03/03A3 bolts (some are packaged as replacement/complete bolts), I will assume that qualifies as a bucket of bolts; not a problem for me but there is not .001" difference in all 30 when it comes to offsetting the length of the chamber. Even the bolts that are packed 2 to the box are identical, F. Guffey |

T. O'Heir, I am going to start listing on eBay, the wife said I have no choice. I started on Craig's List before I realized a reloader can spend a lot of time typing and posting pictures only to find it is a waste of time. When I need a bolt to off set the length of the chamber I have not found a gun parts distributor that that can/will help. I have buckets of bolts, I start by determining the length of the chamber. F.
