I have to wonder if it is Winchester Action Pistol which is the same as RamShot Silhouette? ???
The 6.4 grain load would be a close fit for the actual velocity...
Well, now that you mention that..

I shot a group with 6.5grs Silhouette with those pulled Fed bullets I was talking about. It's in the ballpark..
Yep...Great pull down too. That's close enough performance wise! I have to wonder if Winchester had more graphite coatings on the Action Pistol (seems darker most of the time) than the Ramshot Silhouette which seems to show lighter color tones.
Got to love when the data matches up.
