For handguns I pretty much have it down -- I select practice/training ammo that serves as a good analog to the ammo I carry.
But I'm a newbie when it comes to selecting 5.56 ammo for practice, especially since I haven't chosen any type of defensive ammo yet. What types of 5.56 ammo do you use, and do you select it based on how well it matches your defensive or duty ammo?
I see a lot of 55gr stuff, but I'm not sure if that is the best way to go. Maybe something in the 62-64gr range would be better for all around use? Or does bullet weight only matter for longer distance shooting? My shooting will be at 100 yards or less.
Thanks!
