This time last year, I had about 2000 rounds, less than half of which were "auto-grade" stuff, like MiniMags.
Now, without serious effort on my part (just a few trips to wikiarms.com and a few lucky breaks at the local Bass Pro Shops store), I have probably 6500 rounds. Maybe 2300 are MiniMags, and another 2500-ish are other reportedly "auto-grade" stuff, such as Federal AutoMatch and Champion. Admittedly, I haven't tried those latter two in my auto pistols yet.
On top of that, in the last year, I have acquired four firearms in the caliber (three rifles, two of which are autoloaders, and one handgun.)
So, no, I'm not "soured" on the round. Not by a (wait for it!) long shot...
