One thing I've not seen mentioned just yet is the plight of the semi-greenhorn/materialistic-only-child types like me.
example: Began loading .38 spl. Simple, no? "Hmmm...shooting a Smith 586 so why not .357's?" 'Kay. More brass, or in my case, more ammo (excuse to shoot to make brass). "Oops, prob'ly need small pistol MAGNUM (RAWWRR!) primers now." "What about this here H110/296?", etc.
After starting all over again experimenting with all the different bullet weights and styles for .357, just like with .38 spl., the situation stabilizes...
...until...
"Oh, man. All the old gurus say .45 ACP loads are far better if you handload them. Wayulp, I wanna be an old guru, too. So I better go get me a 1911." (which I've happened to have wanted since age 8) "WOOHOO!! Got my 1911!" (of course, more dies, different powders, primers, brass, and bullets) "Already been handloading .38's, .357 magnums, .357 maximums, and .44 magnums. YAY! I'm a guru now. Lemme just start this first batch of .45's."
Long story short, now I need a factory crimp die, I need to learn how to USE said factory crimp die, I need to figure out WHOSE factory freakin' crimp die I should get, and that's just the factory crimp die, fer crissakes. And then maybe with my SECOND batch I won't wind up with a slide stuck out of battery with a round poking halfway out the back of the chamber. (Did you know that you gotta use a different crimp on autopistol ammo than ya do with revolver ammo?) GRRRRR!
But hey..."RIFLES!!!! I'm gonna be the next P.O. Ackley!"...and on and on...
Seems like everytime I buy something to solve a problem or make a change, I wind up having to buy two more things to go with that first thing I bought.
