I have overloaded hundreds of guns.
It is like handling poisonous snakes or climbing mountains.
You can get hurt at any time if you don't know what you are doing.
I have never been hurt, but I started out pulling a trigger string.
My father started out with trigger strings in the 1940's.
If it were not for all my father's gun designs, I might not be able to afford so many guns to overload.
But there are rewards for destructive testing. One can get closer to the truth.
But most people should not handle snakes, climb Mt Everest, or overload guns.
Most people should just follow the instructions in their load manuals.
