I've been look at getting into reloading .223 for my mini, but I just don't know where to start. My mini has a 1-7 twist in a 14.5 barrel (16 w/flash hider) and a short barrel strut. With all the different bullets, primers, and powders available, I'm not sure what to get. I have a general idea when it comes to fast twists and heavy bullets. I'm trying to go for the tightest groups and still take out the coyotes in my neighborhood. Any formulas that work well for you that you would share?
