6.5 CM fail

I'm gonna swap it over to a Marlin XL-7 action but need to take .008" off of the breech to get it to headspace. .

Are you sure? I know it got bantered about a lot, years back on the Marlin forum. But I've re-barreled a pair of my XL-7's with a few different Savage prefits, and had no issues setting headspace.

Maybe you got some funky stack tolerances?

Cheers

Grab calipers or depth mics.
1. Measure bolt face depth. Repeat for consistent reading. Record.
2. Install go gauge into chamber and measure protrusion. Repeat for consistent reading. Record.
3. If the protrusion number is larger than the BH face number you are good.

I had to have the breech faced on mine, as well. The breech bottomed out on the bolt face when I went to headspace. Then I measured with a depth mic and found I had to have .010 faced off for proper bolt to breech clearance. Many folks that were actually measuring found the same thing.

And many of us who measured, didn't need to machine anything. I just think it's curious, the differences in stack tolerances.

I've had it happen with stock savage barrel & PTG bolt head. The Marlin case head protrusion is about .140 to begin with so putting a savage barrel on a marlin is most likely going to be too close right off the bat.
