I have two Remington .300 Win Mag Mod. 700s, and wonder if the bolts can be interchanged without a problem? I have been told that you cannot, but wanted to get the opinions of TFLers on this. In case it matters, both are stock out of the box ADLs, one has the new bolt lock device and the other, although not very old, does not. The reason for my question is that I would like to use the bolt without the bolt lock in a custom .300 Win Mag rifle that I am having built, but I don't want to use the receiver that the non-locking bolt originally came with. Thanks for your replies.

Remington 700 bolt interchangeability

Yes, and No
Hickman, you cannot interchange bolts from 2 different rifles same caliber or not, without having the headspace re-set, and a gunsmith must do this.
So, in order to do what you want, you will have to take both rifles to a smith and have him change them out.
In THIS case, (since you are having a custom built), take the one you ARE not having customized, to a local smith with the BOLT you do not want to use.
When you send the action in to the smith doing the custom, send him the bolt you want to use for that rifle.
Send him a letter along, letting him know it is NOT the bolt that came with the rifle.
If you are having it rebarreled, it won't matter, because he will reset the headspace anyway.

Having partially dissembled the bolts out of 2 Remington 700SA rifles I have (PSS and LTR), I believe some clarification is needed. Input from gunsmiths or experienced members welcomed.
I have removed the firingpin/striker and bolt shroud assemblies from my rifles with the small tool Remington sells. I have found the assemblies will interchange and function. I have NOT CHANGED the BOLT BODY.
The new Remington keylock assembly is on the shroud/striker assembly.
Since you are talking only about the striker/shroud assembly, I do not see any reason they cannot be changed. Just do not change the bolt body. You can still use the same bolt body that is numbered to the rifle and the headspace should not change.
Am I correct?

Remington 700 bolt interchangeablilty
Hickman: Although I agree if you do not know much about firearms the best bet would be to take it to a gunsmith there is another way to do it. All the gunsmith is going to do is put a set of headspace guages in both guns to see if they are safe to fire when exchanging bolts. You can purchase a set of these guages yourself from Brownells co. YOu will then have them to check your gun from time to time if you are concerned about the headspace going bad after many rounds have been fired, especially hot handloads. You can even get by with only using the no-go guage only. If the no-go guage allows you to close the bolt it is not recommended that you use this bolt. There is also a go guage that tells you that the gun has enough headspace to enable you to close the bolt on factory ammuntion. Bolt interchangabiltiy is no big mystery, it simply involves understanding how headspace works. W.R.

Yes sir,I don't see a problem here, as the headspace is measured off the bolt body, and the way I understand it the body's are the same...just the pin, and shroud.....
I was told by a VERY prominent smith the pins are longer than the old units..........but if the bodies are the same length, then I would think the difference in length would be at the shroud only.
Which would not keep the pins from being interchanged.
I personally do not know as I am not a smith.

Pin and shroud length.
Yes, the new shrouds are longer and firing pins are longer under the shroud. The shroud to tip length is the same.
My LTR has the longer shroud, but it is not cut for a lock. The older PSS and my BDL have short shrouds. Initially I planned to swap the assemblies to put the lighter, shorter shroud on the LTR, but I am going to forego that as I am selling it.

tried swapping the shroud assemblies
I took both bolts apart, and as noted above, the new models with bolt locks do have a longer pin, but also as noted, the extra length is on the shroud end. I swapped the assemblies, and they work fine in both guns. I used a go and no go headspace gauge on both rifles before and after, with good results not affected by the swapping around. One other difference I noticed is that in the newer shroud assembly, the firing pin spring appears to be a bit longer and is somewhat curled up, whereas in the older assembly the firing pin spring seems shorter and lays flat. Thanks for the advice.
