I've been meaning to discuss this topic for a while, so here it goes..... One of the initial literature guides I used regarding 9mm defense ammunition came from the website http://www.chuckhawks.com/ammo_by_anonymous.htm. Under the 9mm section the website states the following in regard to 147 gr JHP; With that said could any of you please explain where/how this opinion came about regarding 147gr 9mm? How has the 147gr 9mm evolved since whenever this article was dated?(Over the past 3-4 yrs, I've fired hundreds of 147gr WWB JHP flawlessly out of my Taurus PT92, so I'm confused on why the article says it's prone to jamming.) Appreciate all the help and info you guys can give me! p.s. Tried using the search function for this ? but failed to get a precise answer.
