Barrel Bedding

[Squatch]

Here is a segment of an article I have saved that I found when I first started researching the Grendel:

They also have a tighter barrel extension fit because the Grendel’s heavier recoil “explores” all the loose spots, and the barrel will settle in a different position each time if given the room.
Wandering groups in well-worn test rifles also taught Alexander that he needed to bed the barrels and gas blocks. Under a microscope, the surface of anodized metal looks like a forest of microscopic Christmas trees. Over time, those Christmas trees lose their tops and the rifle’s groups open up. Alexander beds the barrels with 2440 Locktite, which fills in the gaps but allows the barrel to be removed with standard tools. The gas block is seldom a problem, but has bounced loose on a couple of rifles. Alexander doesn’t take any chances and beds both parts on all his rifles.+

Hope this helps.

I got on loctites website and im currently considering 2422 thats the ultra high temp blue, it has a melting point of 650. If i can find something similar to 2440 but ultra high temp ill go with it
