I pray you never are in a situation where you have to use one (or more) of your hand loads. They will bite your a** in any criminal or civil trial that may result from that incident - lethal force justified or not.
Masad Ayob can explain better than I the reasons you should not use hand loads in your carry gun. But in a nut shell, to avoid legal problems, use factory loads in your carry gun. Crooked and uninformed lawyers/DA's will do their best to bury you if you use a hand load, and a jury or Judge un-knowlageable about firearms will convict. You may wind up paying big bucks to the crook (or his/her heirs) who tried to rob/rape/kill you, and/or get to spend many years behind bars, even though the use of lethal force was justified.
Hand loads are fine for practice, but not for carry.
Check out one of Masad's many articals on the subject.
In answer to the original poster's question - HECK NO! Just because it works in the tester's arm does not mean it will cycle in mine or be as accurate - even if they are the same make and model.
