For legal reasons, i use factory. If ever i find myself in the regretable position of defending myself, i dont want to have to defend the way i designed my ammo. I will let the experts of manufacturers handle that one for me. I can not site any case in which it has become a concern, but with all the other worldy things to come out of our courts at times, i dont find it worth the extra worry. With all the hipe in wording over semi automatic firearms, i can easily see hand loads being depicted as some sort of beyond deadly WMD by uninformed anti RKBA ers.
