savage barrel swich to marlin XL7 & XS7
HAVE ANY OF YOU FOUND THIS TO BE TRUE
This copied from www.24hourcampfire.com
The diameter and thread specs are the same for the Savage 110 series barrels and the Marlin XL/XS-7 barrels. The potential problem is that the Marlin XL/XS-7 bolt face is recessed more than the Savage 110 series, so it is POSSIBLE for the front of the Marlin bolt to come into contact with the rear of a Savage/Stevens barrel before proper headspace has been achieve. This would create excess/long headspace and the case WOULD stretch and COULD seperate when fired. To be SURE of getting proper headspace, I have cut 0.1" off the rear of the A&B barrel in 257 Roberts that I installed on a Marlin XS-7 action. I had to recut the chamber, since cutting 0.1" off the rear of the barrel created a "short chamber" situation. While you might not need to go to this extra effort, I think that it is a good idea to do so, to insure that this is a safe barrel installation. As with many things, some people are going to say that the barrels are 100% interchangable without any modifications, but that has not been my experience because of the the differences in the recess of the bolt faces.

...No reason to cut the bbl. any...It's the bolt head that needs the work on... :-[

but if you do that then how can you put a savage barrel back with that bolt head?

...Now ask me that question again..Blue Av... ::)...Now how is cutting the bbl. going to change that dimension... ???
Re: savage barrel swich to marlin XL7 & XS7
I am thinking the same thing. The bolthead is the problem, not the barrel. It says he cut the barrel, which made it a short chamber, so he had to redo the chamber. Now wouldnt he end up with what he originally started with? Doesnt the chamber have to be cut with a specific amount of case head protrusion? So it cant really be changed, can it? Or am I just missing something here?
Seems like maybe truing the boltface mighta been a better option, if it would allow for the clearance.

I did this swap and never had an issue.

Re: savage barrel swich to marlin XL7 & XS7
savage has a working system with there barrel and bolt relation right?
so why would it be the savage bolt that is wrong for the action when you introduce a barrel not intended to be used on the savage action?
why can it not be that marlins barrel (or maybe just that one even) is not a perfect match for a savage action?
( not saying you can't, just was not built with that in mind)
can you say that the chamber was cut right to start with? not a factory error?
what is the spec depth of a marlin bolt head?
Re: savage barrel swich to marlin XL7 & XS7
Ok, I have both types.
The Bolt face on my XL-7 IS NOT recessed more than my Savages. YES the barrels are the same Thread spec. YES the Savage nut wrench fits both, YES the nuts are the same. As for why the author is such a boob, I don't know... Were the purported recession of bolt face an issue, he would have merely had to install the Savage bolt head; they are both floating. They come apart the same way.

Darkker, Is the savage head to marlin bolt a swap that can happen with no machine work? A friend just bought a marlin and would like to try a few of my savage barrels. Thanks, Bill

Cool, you guys can tear your guns apart and check swapping parts for us! :)

wow that does not make sense what that guy was doing.

Can someone measure your "0.473" bolt face depths? I only have the LA 223 in the photo.
Also, exactly what is the difference between long and short action bolt heads? Side-by-side photos?
Thanks,
Bruce
Re: savage barrel swich to marlin XL7 & XS7
If the depth of the bolt head on the Marlin is .140", that means the chamber is shorter than on a Savage barrel.

Nice presentation! Thank you!
