I went with the Brownell's Satern 5R button barrel. I would have preferred a cut rifled barrel but this one will provide adequate service I think.
I went to the range today in the monsoon we are having here locally.
I was about 7-8 inches high and off the paper, plus the three shots landed next to an existing bullet hole (looks like a 4 shot group - the existing bullet hole doesn't have the dark ring around the hole).
I forgot my cleaning rod so I didn't get to do my typical barrel breakin, so I didn't get much accomplished today. Just as well. The rain prevented any chronographing anyway.
Regards,
