.....yeah, but I'm going to stick with "anonymous guy on internet forum" because everybody knows the big greedy reloader lobby have conspired to sell you an extra ppound of powder when you screw up. :D
 
9MMand223only - you are certainly free to experiment with mixing powders and any other off the book reloading practice you like as long as you are not putting others at risk i.e. at the range. But, to suggest it to others is irresponsible.
 
Take it outside,
Poke it with a stick.

If it doesn't entertain you,
Hit it with a rock.

If it still doesn't entertain you,
Pour gas on it and shoot fireballs at it.

I suggest roman candles, good standoff distance...

Get it 'Right' and you will get a mini-mushroom cloud!
That's ALWAYS entertaining...
 
if you do end up loading the mixed powder, despite the thread of suggestive "NO's", please let us know how it went. and if your gun explodes, please post pics, everyone likes pics of KABOOMS.

it would be kind of cool to take an old beater revolver, take some pistol powder and some 50bmg powder mixed, take some high speed pics of the huge fireballs. maybe fun in a ransom rest about 25 yards away though. probably wouldn't even burn and you would just have sticks of powder flying all over, who knows

To say that I am astonished to see people advocating actually using mixed powder on a reloading site is the understatement of the week.
 
Of course, the correct answer, is to dispose of it properly, preferably as fertilizer. That being said, I discovered that a blend of W-231 and Unique, loaded to W-231 specs in 45 Colt with 255 grain cast bullets produced a very accurate and safe load, indeed. I cannot recommend such a practice. If you can get new powder, by all means do so, dispose of the mix, and don't let it happen again. Store your powders away from your reloading station. If you never allow but one powder at a time at the reloading bench and always empty your powder measure back into the original container, it won't happen again. Generally, it's not practical or possible to separate two different powders once mixed. An exception might be AA-9 mixed with H-4831, where a flour-sifter might do wonders.... An ounce of prevention can save you from many pounds of regret, remedy, and cure.
In times of dire shortage, I would think carefully about that mixed powder. If not 100% certain of the safety, even then it should be disposed of. Consider it contaminated. Consider it an educational expense and, "Don't cry over spilled milk.".
 
This is pretty useless. If people want to mix, they mix, if you don't don't.

Just don't mix titegroup with rifle powders, ok boys?

I was not among them (referring to post #9).

I've never mixed powders. And don't plan on it. I figured out decades ago to only have one powder on the bench at a time. And I didn't learn this the hard way. I mearly proactively thought it through, before I made a mistake.
 
9mmskeeter,
you haven't said what caliber you were thinking of using this for. I have also worked up loads for blended powders but there is a fine line to doing it safely.

IF YOUR THINKING OF USING THIS FOR 9MM, FORGET IT.
9MM is already a high pressure load to begin with and is the wrong caliber to experiment with.

I dumped a different powder into Unique one time by accident and it was during one of the powder shortages, I wasn't about to throw it away.

The two powders were kindred to each other and also beside each other on the burn rate chart.

I won't tell the proportions either because I won't be responsible for someone else trying this.

I've been hand loading for over 40 years and this isn't something for the more in experienced re-loader to play with.

I would never try this in a high pressure load of any kind.

Pathfinder is using low pressure loads as I did, You would be better off disposing of it, but don't dump it on a vegetable garden for fertilizer, there are other things in smokeless powder that will end up in the vegetables that you don't want to be eating.
 
Call me a stickler for excitement. I did 4.0 of the mix and it shot fine, extracted, and was accurate. I don't know how much 231 was present, and I'm sure the results will vary each time. That still makes it a wild powder and it probably would be best used as fertilizer.
 
I don't know how much 231 was present, and I'm sure the results will vary each time.

Why would the results vary? Didn't you mix it up? Should be evenly dispersed.

Like LE-28, I'm curious what caliber you're loading.
 
Any mixed powder should be disposed of (not by reloading and shooting). Reading of some people actually using it does not really surprise me but to talk about doing it on a forum is just not right. I think it may tend to make someone new to reloading be less cautious which is not a good thing. It does not matter how long anyone has been reloading, using mixed powder is just wrong. Reading of doing this makes me realize a forum may not be the best place to get advice on reloading.
 
A forum like this one can be a very good place to extract useful knowledge from the experience of many others, including their mistakes. This isn't the gospel. But some people are given to careful experimentation that perhaps most others shouldn't attempt. Like P.O. Ackley, for example; many of his experiments produced results of little value while others were worthwhile. He did things that should not be done by most of us, as also Dick Casull, Elmer Keith, John Linebaugh, and many others have done. No, you shouldn't mix powders, and if by mistake you do, you should dispose of it. You could blow yourself up, and if you do, your blood will be on your own head. Perhaps the afore-mentioned personalities were thought to be reckless fools at one time. Now, they are quoted like the gospels. The hearsay on the internet, including this forum, should always be considered with a spoon of salt and compared with other sources of information before blindly rushing forward beyond the pale of conventional experience. If you think you want to try a load with a very high potential for disastrous failure, maybe you should strap the firearm securely in a thick iron box and pull the trigger remotely with a string as you crouch in a foxhole or bunker. People have done this. Some of us just have to find things out. Some of us find a way to do some things that we wouldn't recommend others do.
