Finally got an old dinosaur put together and to the range.
Picked this revolver up a couple years back. It is a 1966 Herter's Sigle Six in .401 Herter's Power Mag. The top-strap had been already altered. So I just went and altered it some more and put a Weaver rail on top. Picked up a fairly period-correct 2.5x Redfield from a fellow HPA'er a while back. A set of Weaver rings and I was off to the range.
It took a few at 50 then back to 25 yards to figure where I was. Then out to 100 to see if I could hit the broad side of a barn. I am an admitted lousy pistol shot.
Ended up with 2 groups at 100 yards that were nearly identical.......... one flier and a tolerable 5-shot pattern. This is only the first load I have tried. So the gun may like something else better.
These are 180 gr. JHP's at around 1700 fps at 100 yards........ 5 shots.
