While the bolts do fail, it isn't often. But keeping a complete spare bolt is a great idea. Various parts do fail and swapping out bolts at tthe range is an easy way to prevent ruining a good range session. Just make sure the bolt headspaces properly before using it.

After insuring that the bolt gauges within spec., I would complete it, install it and proof-fire it. Then you have a spare bolt.

These things headspace on the case mouth like a 45? We use to put pieces of tape(Masking) on the case over the primer and see how many a garand needed to show some resistance and then use a mic to measure the tape...It is fairly uniform...I only use it one time to headspace a garand and have fired many rounds without a problem...This was years ago, maybe 15 years,someone had put it on the internet...I had the rifle checked out by a gunsmith a couple years ago and he said it closed on a go and did not on a no go...I do not know if these were field gauges or what

If an Original bolt (to the weapon) fails, one might have much more serious concerns than digging out a replacement, little dot, very specially marked with those little stamp marks from a book that says they are original, new bolt to slap in, and keep shooting.

If a bolt fails, due to headspace error, or reloads not to spec, one may find themselves in a hospital asking for extra jello a few days later. That spare "IBM" marked, "expertly" reparked bolt may still be in the range bag in the trunk of someone else's Honda.
