Well said SturmRuger. I've been a Ruger fan for the last 25 years and since I do tend to push things a bit hard with my hunting loads, I rely upon their strength and design. But the Colt's of the last couple decades are also very strong. Double charging just about any powder load in a pistol case is leaving the door open for disaster. Too much crimp on a heavy load can be detramental to the weaker handguns. They might not blow up, but I've even broken the frame lock on a Taurus model 66 when the loads were too strong. No real signs of too much powder, or split cases. Not even flattened primers, But frame damage was the result.
There have been comments about using powders that can't be double charged. Great idea. And that's what I do. But, even a 20% extra charge can be dangerous. So, All warm loads should be loaded single stage. Each one should be weighed after thrown. No,, Not every fifth one. Every charge. I also have a Dillon press. It's awfully tempting to speed up the reload process just because I can. But I don't with the hot loads. The Dillon powder measure is very reliable. But we need to be careful with heavy or even some light loads. I've been reading about light charging the .243. I've resorted to not doing it.
Owner of this mangled Anaconda admits his search for the one powder that fits all, allowed for the double charge. He admits that must have been what happened.
We should be thankful for his honesty. If this thread saves one firearm. One life or injury to someone by them making a change to their own reloading processes to be one step safer. That is worth his humility in public. He's lucky to be here to shoot another day.
Hopefully there are many that have read this thread that will analyze their reloading practices and adjust if neccessary.
