| Is this a bad idea, assuming the bolts were never used in a different upper, or is it wise to stick to one bolt until it is broken, then bust out the other one? |

Most people agree the bolt and barrel (and its extension) break-in to each other. While breaking in, parts usually wear a little faster, once broken in to each other, parts usually wear a little slower and can handle a little bit more stress before breaking.
SO, if you keep swapping around bolts, the break-in process never ends, so the parts will wear a little faster and be just a little more likely to break under extreme stress (just a tiny bit more, swapping a bolt is NOT likely to break because it hasn't broken into the barrel yet, ITS MORE OF A CASE OF if you overstress the parts greater than what they are designed for, the part that is broken in is a tiny bit more likely to break later than the part NOT broken in). I think most people will also agree this almost a splitting hairs argument, it makes very little difference, BUT, if you have no other reason, then why NOT go the direction that produces less wear and makes the parts a little better to handle stress. If you've got a good reason to swap bolts, I don't think it would be a problem, but, like stated already, if you think sharing time between BCG's will make things last longer, it won't just keep the 2nd as a spare to be put into use when the 1st goes bad, or save it for a 2nd rifle. |

I would keep the spare as just that.....a spare. In the event your current bolt fails, insert the new bolt and gage it. If it passes, carry on. |
