My reason for liking Mini Mags is about the same as everyone elses. Just looked over an accuracy chart I've been compiling over the last 4 rifles I've owned (CZ 452, 455, and two 10/22's), and until last November, I used almost exclusively high velocity stuff, and mostly HP. Mini Mags hover around the top 5 most accurate in all of them, never had a misfire that I can remember, nor a feeding issue.
