XP bolt
I'm going to rebarrel my XP to 221 FB. The bolt I have is for 7 BR, so I suspect that will go to ****. (the 7 BR barrel is not in good shape and I don't want to get another set of reloading dies etc--I have the 221 FB set already)

Anyway, I'm looking at getting a bolt from Pacific Tool & Gauge. I want to make sure I get the right one. From their website, it looks like I’d want has these dimensions:

Firing Pin Tip Diameter = Standard Diameter (0.075”)
Bolt Face .223 (0.380”)
Remington Extractor Cut (there are other options)

I’d be grateful if someone could please confirm that this is what I want, and if there are other options, especially better ones, I’d like to hear about them.

Need the .223 bolt, standard firing pin and standard bolt diameter

Extractor, go with a Sako style (just my opinion)

I prefer the m16 style extractor. Just my preference, and another option. I would also bush the bolt face as Chris suggested.

Why not trade your bolt for the correct one? If your ordering a bolt get the small firing pin hole. You'll need the small firing pin but you'll get better ignition. I prefer rem extractors for 223 size cases.

I think I might know someone that has two or three XP Bolts with .223 bolt faces. I think they would be willing to trade one if your bolt is in good shap

The bolt from PTG will need to be fit by a smith. I bought one myself and it is not a drop in exchange fit. I dont know if they make a bolt from a sample ( like the one you already have. They also would not take the bolt back for refund. You should be aware and call them about your idea of exchanging bolts. I eventually sold my bolt at a big loss. Bruce

Looks as though I'll be able to swap bolts. Thanks, everyone!

With the help of a kind lister (who swapped bolts) and my gunsmith, the 221 franken pistol is now together. It has a barrel, stock, receiver, and bolt from different guns, and shoots well.

If you do get a bolt from PTG you can specify the bolt diameter which will allow you to get a better fit in the rear and prevent the bolt from rocking which is a feature on custom bolts. You will have to measure your current bolt diameter and see how much it moves in the receiver and add to the diameter when you order.
