Out of 30+ doubles I have owned or own ATM
and probably 50+ I have shot, I have only had ONE
that doubled when i first took it down the range
and that was my Westley 500/465 - which promptly
went to the gunsmith and had the thing adjusted
- problem solved.

That's a small percentage.

Not too sure on your Jeffrey
- what did that turn out to be ?

From my experience, Doubling is more often than not caused by the operator.

I also saw that the original poster had a Merkel 470
which I also have so I assumed that it unlikely to
be the gun having seen quite a few new Merkel's
being shot.
