no, i can't think of a case where a lawful ccw had trial issues over handloads. but consider this- many non-gun types ridicule us ccw's as being paranoid. how many times have you been held at gunpoint, they scoff. but you and i both know that it is a very real possibility, and we're choosing not to become victims. it is that same "paranoia" that keeps me from modifying the trigger on my ccw, that keeps me from decking out my home defense shotgun with fancy tactical plastic add-ons, and that keeps me from carrying handloads for personal defense. just because i've never known anybody who has had these things brought against them specifically in a trial does not mean it is not a very real possibility, and i am thus choosing not to become a victim. but do what thou wilt, it's a free country.
. in a perfect world, none of this would matter. personally, the urban liberal/socialist political climate has me feeling quite paranoid- the freedom to defend ourselves is slowly being dissolved by complicated new law, piece by blood-earned piece. if i end up defending myself before a jury, i want every advantage possible. six of twelve will be liberal, five of those will be anti-gun. the other six will be conservative, and there is greater than one in a hundred chance that one of those six will be a handloader or a ccw holder. it's no time to play idealist when my own freedom is at stake.
my first ccw class was a semester-long gig through the police academy. most of the folks in the class were on the l.e. career path. the instructor couldn't stress enough the taboo against carrying handloads, and i respected his warnings. his concerns have been echoed by the state-certified private instructors i've trained with as well. there must be a reason for it.
