Re: 45 Long colt
yep the ol W571 is obsolete and isnt made anymore, but as Bindernut mentioend HS-7 is interchangeable and you can use HS-7 data to load with older lots of W571.
It is a bit too slow for .45 colt loads unless you are loading hot for a ruger or T/C singleshot.
It takes 43 muscles to frown, 17 to smile, and 3 for proper trigger squeeze.
The latest caliber or gear is no substitute for experience and skill. Rifles and cartridges don't make hits -- shooters do.
Fact of life:
After Monday and Tuesday, even the calendar says WTF!
