Well, alright, one more time... <sigh>
And to your last comment, if by saying you would not bet your life on it (the gel tests), is it because you would in fact ignore the results in the gel?
No, not IGNORE them, just take them with a very large grain of salt, and take steps to have a response if those results do not obtain in real life.
People don't run flawed, faulty or bad experiments.
MOST people don't INTENTIONALLY do so, but DOES happen. Additionally, experimentation designed to render results supporting
a priori conclusions happens more often than you might think. Peer review minimizes a lot of it, but it's still out there.
I'm not a firearms professional/lab procedure expert
I'm not sure what constitutes a firearms professional, but I spent 20+ years employed in R&D and QA/QC labs where lab procedure and statistical analysis was a way of life.
but I thought that the value of gel was not an absolute measurement, but an agreed to standard on relative performance of bullet behavior
You make my point FOR me. Ballistic gel is AN indicator, not THE indicator of projectile performance. As such, it should be regarded as A determinant, not THE determinant of what may work best in social situations. How many times a particular round effects a stop on a determined attack, versus the total times said round has been used in these situations is another, probably more valid determinant. Unfortunately, it is difficult and unethical to go out and "actively gather" such data. We must wait for such incidents to happen. THIS is the value of ballistic gel tests, but they DO have their limits.
that factor in to betting ones life on the results
.
Again, ballistic gel tests are AN indicator, not the SOLE indicator. I won't ignore them, but they won't be my only basis for picking what I carry. When I pick what I carry, I AM betting my life on my decision. I want that decision predicated on LOTS of information, including that obtained from actual shootings, despite how grizzly that may sound.
Are you saying that placing one cartridge of each type in the mag is proven to be a better solution?
Absolutely not. And "proven" is a big word. Since there haven't been a great many incidents in which a person firing for his life has emptied a magazine-full of rounds with different projectiles into his attackers, how could I say that ANYthing about such a departure is even SUGGESTED, much less proven? I don't AGREE with what OP's friend is doing. I just don't think it's quite as implausible as many on this thread seem ready to conclude that it is.
Okay, THIS TIME, for SURE, I'm done.
