CW and Fastchicken,
Thank you both for your points of view on detonation/non-detonation. It's good that we discuss these things here; that's what a forum like this is for. It makes me wonder if someone should post a thread on "Detonation theory".
Or perhaps research the theory. I'm sure someone, somewhere has done some sort of research on this.
I can recall back in the late 80's when I first started to reload the 45 Colt. I had a subscription to "Guns and Ammo" at the time and one month was an issue with a horrifying article on blown up guns. I wish I could find that issue today. Nonetheless, this is where I was first exposed to the detonation theory and as I recall from the article, it was predominantly large case volume ammo that was most subject to this condition....or at least the theory. I was horrified by the photos of guns bent, twisted, and torn apart and hoped I'd never experience this in my lifetime. Since that time, I've held to the detonation theory and always (like CW has stated) tried to load with powders that fill more than half to three quarters the case volume. This keeps me clear from the possibilities of detonation (if this truly does happen) AND it ensures me that if I accidentally double charge a case, it'll overflow and be absolutely obvious that I've made a mistake with a load, hence preventing any type of accident like this.
It is unfortunate that I haven't had the time to describe or convey this point to Thane prior to this occurrence....be it double charge or detonation...as he began loading the .44 mag on his own. I believe it was only after this occurrence that I had described the detonation theory to him and thought at the time that this is what has occurred to his firearm. Now that I've had time to look over load data, I'm 50-50 on detonation or double charge. As I said before, we'll never know. Thankfully Thane wasn't hurt and he never thought twice about quitting shooting/loading as I have done. Perhaps it's an age thing???
As a point of respect for the powers at hand here; Thane and I were in shock at how a barrel (thick and heavy steel) could move, tear, and bend as it did yet even the smallest part of the fragments attached were absolutely unbendable by us, no matter how hard we pressed or squeezed on them. This is an unbelievable amount of force, energy, and pressure that caused his gun to blow. If any large part would have let go from the mass, it would have easily gone through our bodies and easily killed one of us. This is part of the reason why I have been literally shaken to the bone about shooting and reloading. No one here ever wants to experience this, believe me!
PLEASE!!!!! Use caution when loading and shooting! And PLEASE!!....if you ever offer advice to a loader (especially a new loader), be responsible and work with them as much as possible. Don't just throw out a load to them as the guy in the gun store did with Thane.
BE SAFE! THINK WHEN YOU ARE LOADING AND SHOOTING! STAY ALIVE!
