Quirks?
Yup! My name is Steve and I'm an ammo snob. Especially ammo (bullets in particular) that I trust my life to. I don't care about the caliber, big vs. small, bolt, auto, single-shot, revolver, or whatever. If I'm going to use it for anything off the range like hunting or SD, it has to be stuffed with the latest, greatest, custom, premium ammo money can buy. With emphasis on premium or custom cast bullets made or loaded by the usual suspects. And I really dig the High Energy and Light Magnum concepts using premium bullets by Federal and Hornady respectively. I really wish more manufacturers embraced this idea.
When I enter my favorite emporium for hunting or SD ammo, I turn my nose up at the regular off-the-shelf stuff by the major makers. No Core-Lokts, or Power-Points for me. Federal Classic? No way! Okay I have some of those on hand. But that's only because I couldn't find any 150 grain Ballistic Tips and it did pain me to buy them.
When it comes to SD ammo I even tell my department which to buy.
I believe that bullet technology and manufacturing techniques in the last few years has allowed us to use calibers for applications that a few years ago would have required a jump to a larger caliber. There is even a better understanding as to how cast bullets behave on firing and the optimum hardness to get them to perform their best in specific applications (explainations on Garrett Cartridges website are examples).
