What you're asking yourself is 'was the sample size statistically significant and representative?'

Most of us think it was.

Especially since the results were near identical for each sample.

In my view, a specific reason to NOT shoot older barrels either pattern welded or fluid steel was not demonstrated.

It's obviously an individual choice.

Note how many similar guns DID survive the weekend, and many other weekends.

It's only the plane that crashes that makes the news.
