Ignition is terrible, velocity is terrible, and velocity variations is terrible.
I was using it to break in a 257RAIR, 260 [small primer], and 7mmRM out in the desert reloading in my car in October.
I get twice as many shots without Copper fouling. So terrible for those cartridges but great for break in.
The word 'forum" does not mean "not criticizing books."
"Ad hominem fallacy" is not the same as point by point criticism of books. If you bought the book, and believe it all, it may FEEL like an ad hominem attack, but you might strive to accept other points of view may exist.
Are we a nation of competing ideas, or a nation of forced conformity of thought?
