The new powders do bear alot of performance merit over older powders. I worked with 2000MR in the .308 when it first came out. I was pushing a 175 gr sierra matchking at 2985 fps before I started getting pressure signs. And the pressure signs was only loosened primer pockets after 2-3 reloads. I could have easily gone higher and pushed the cases to extractor marks and probably got another 100-150 more fps.
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!
