“I have only shot 20 or so rounds but am very pleased. I had no feeding issues in my Glock 35 (5.3" brl). They averaged 1022 fps on a 34 deg F day ( 5 shots, LabRadar chronograph) with a range of 54 fps (not great). But I averaged just under 2" for three 5-shot groups at 25 yds. from a rest, which is quite good for me. I alsoshot 2 rounds into a dry ponderosa pine log (end grain). They penetrated an average of 2.85" and were heavily deformed but they retained 172 out of 180 gr. My unprofessional guess is they would do a serious amount of damage to soft tissue but would lose a lot of energy if they had to go through a barrier before hitting the target and may not break heavier bones very deep inside the target.”
