It's true, what worked one day may not work the next. It's the same in all these discussions, instead of just taking the other guys point and accepting that it may be valid, it becomes a peeing contest to try and change the other persons mind,
When you have as many variables as you have with guns and bullets, there really is no one way or one right way that works all of the time.
Guys have died from 1 shot from a 22, or a slingshot, and lived after 6 rounds of 45. So what does it matter to prove that one way is better than another?
what works for you should be enough, hopefully you won't need to find out.
Sometimes we all take things too seriously, all you can do is try to be prepared for what may happen, and hope that it never does.
Since shooting became more popular in the last 15-20 yrs, everyone is trying to make a buck with whatever they can market to the public as the latest greatest thing to ever happen to the sport.
Most of it is nonsense, some is relevant, but when you are dealing with 2 or 10 things that are very similar and are job specific, "like a bullet" there isn't going to be a heck of a lot of difference between them. It's more where you placed them "IMO", and which is easiest to handle.
