I have used a ton of them but mostly in Glocks and for informal bullseye and skills practice (not USPSA matches). I loaded them over Accurate Arms 2 and 5 powders, with medium to warmer than medium charge weights, based on the Western reloading manual's recommendations. I have never had a problem with them. My OAL was around 1.106, but I don't adjust it much. I did shoot a 49/50 4x with 115 HAPs and AA5 on a B8 center at 25 yards freestyle. So, I pretty much respect these bullets, at least in my handguns.
