I've had a .243 700 for nearly 40 years, no problem, until I ef'd up and had a stuck case - hammered the bolt handle with a dead-blow.

And a 725 (predating the 700 in manufacturing) for close to 30 years. No problem.

I have re-silver-soldered-on several other than my own 700 bolt handles, all having been hammered open .... None, to my knowledge have had a problem since.

One should probably not do chit requiring hammering open....

That said, there are good soldering jobs and not so good... production oriented jobs may or may not have a higher percentage of the latter.

The only true cost of having a dog is its death.
