Ya know, sometimes it just pays to walk away from that "deal of the day".
At one of our monthly LR matches, a good friend's wife had her gun blow up on her.....Hubby had done the reloads and wonders if he perhaps used the wrong powder.....won't be having multiple jugs on the reloading bench again!
She's okay (got some shrapnel cuts on the face/hands but nothing life threatening).
He THOUGHT about taking the action to a NDT shop then reconsidered. IF you find someone who does that sort of work (and are they gonna certify the results), do you trust him to know what he's doing w/ something that contains upwards of 60K-80K psi just inches from your face?
What if, just what if, the action were to blow up again under normal pressures due to any existing & unseen damage from the first blowup?
If his wife were to be injured again, he'd never forgive himself.
Tossed the gun, bought a new one.
Peace of mind is a very valuable commodity.
A thought........
