I bed around 5 of my own rifle actions a year with devcon steel putty.

I pay for a new jar every year and write the date on it.
They use Devcon at Boeing and are always careful about the date.


I do dozens of bolt handle threaded inserts per year with Bob Smith Industries BSI-201 Clear Quik-Cure Epoxy.

I store it upside down so it is ready to squirt out in one second.
It is 5 minute epoxy that gets into the grain of the wood AND bonds to metal.
