Gotcha.

Glad you are ok..

Detonation as the gunsmith used it, I'd think meant what happens when you use too little of some slow powders. Don't fill the case and the powder doesn't burn correctly and causes a huge spike in pressures. lots of times referred to as a secondary explosion or detonation. But not something you'd think would happen with pistol powder. I've been reloading since 1959, and don't ever use pistol/shotgun, powders in a rifle case for something like fire forming.

That stuff leaves a lot of unburned powder in the barrel, if this happened after a long string, you may have had a bullet stuck in the barrel.......happened to me once, but I noticed the stuck bullet before the next shot.

The previous shot mad a hole in the target.

glad you are not hurt.

If you have a digital scale, you might weigh the rest of the loaded rounds. It's a fairly quick way to spot any double or missing charges.

I've learned not to trust powder measures at all. I have two of the top brand measures and both of them will occasionally get the drop tube jammed enough to prevent the full charge to drop. But on the next one the extra powder comes down and you have an overload. This has happened too many times, even with short cut powders. I haven't seen it with the super fine ball powders though. So now I put each charge on the scale enough to catch the real light or real heavy loads. Slow but I don't shoot that much center fire at a time anyway.

At least you still have your parts connected.

Glad you're okay. By the way the above system must be correct. It's how I do it.

easy with a flake powder like blue dot to get bridging in the drop tube but OP states he was weighing each charge and then filling a case. all I can say is thank God you can still see!

You do know why Trail Boss and SR-4579 were invented?.

P.S - glad you're okay. And I've played with Blue Dot to some degree, but luckily (I suppose) it never gave me any sort of accuracy.

Good example of why powder manufactuers don't know [bleep] ...........sarcasum

My first and only double charge that I caught was in 45acp coming off a Dillon turret press. Made a big impression. I now look into every case that rotates around the shell holder after throwing a charge. I also use a shell block/holder for rifle cases and look into every case before seating bullets after powder is dumped in. I've saved myself a lot of pain and money by doing so.

I have read that SR4759 is discontinued

Happy to hear you are OK and have survived a loading mishap of some sort. I'll just casually suggest that human error, as much as we'd all like to believe it "wasn't me", is usually to blame in these instances. After a surprise with pistol powder in rifle rounds, I've changed my practices accordingly. I, like you, am quite meticulous in my loading habits...but I've been around long enough to know that most [bleep]-ups in life belong to those who where there to witness them.

I have to ask...why Blue Dot in a rifle cartridge?

I've been asking the same thing for 30+ years.

Easy to make mistakes, probably so double dip. Wonder what a chrono would of read on that load. Just something that makes you more aware of what your doing.

Has this been answered here?



Anyway, I do not use Blue Dot powder. It is a good powder but has a freakish nature to it. There is a warning not to use it in the .41 Magnum. Why, who knows. Just like 800X for the 10 mm. Wrong combination of bullet, load density, temperature and other varibles can cause a problem without warning. Best just to stay away from it.

Glad your okay.
