I load three levels of 380; +P, +P+, and atomic to correspond with 3 levels of 380s manufactured. The least of which are the Kel-Tec P3AT and the Ruger LCP with case support as bad as 0.29", chamber walls as thin as 0.27", a barrel and slide mass as low as 4.5 ounces, a 2.76" barrel, and a 2# to start 7.5# to finish recoil spring assembly. And even those wimpiest 380s will shoot my +P and 90 gr and Buffalo Bore 90 gr +P ammo at 1100 fps.
I have only experimented with Power Pistol and Bullseye, 90 gr, 115 gr, and 158 gr bullets.
Both of those powders get-r-done, but I suppose almost any pistol powder would.
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?
