Is there anyone in the forum that has any experience with INTENTIONALLY mixing powders?
I have a load that I am trying to work up to achieve the highest velocity I can achieve, and maintain some stability for the round. I am getting closer and closer to my goal, but still not quite there.
Before the "Never do this" or the "not worth blowing up" crowd jumps in, I already know these things and don't care to hear the retoric...

I would suggest that you start by reading any, and several of the leading authority manuals on this subject. Call the Powder manufacture on this and talk to them. Talk to a ballistics engineer. Or even call some of your bullet manufactures. Sound simple but it will probably only take one mistake to be a serious injury or deadly.
Even duplex loads are taboo IMO

Interesting question. I'd follow jeh7mmmag's advice and call the powder manufacture.
Then I'd get a degree in chemistry. Burn control rates are partially controled by the shape and the coating.
I think I'd go as far as taking ...well never mind. This thread would get locked.
I'd be curious to find out what you have learned.

I blended some IMR 7828 and H4350 one time... on a complete accident Now I have a new rule, only one can of powder on the bench at a time! At least I caught it before I blew something up, poured it in a pile and lit it up, kinda cool to watch. matt

Sorry, I don't think you're gonna hear anything but those responses. This is a foolish pursuit. Anyone that thinks they can blend powders at home and come up w/ a better recipe than the powder manufacturer's is delusional. While its true that powder manufacturers have a good idea how certain powders, coatings, shapes and even powder blends will perform, the fact is they don't know with certainty until they perform their proof testing. If you don't have the equipment to do so you are engaging Darwin Award type activity. This thread should be locked... David

Since you have the other post about how much you can compress a load, why not just select a slightly faster burning powder... it seems like thats what you are trying to achieve.

Exactly!
Don't expect an answers anytime soon... Most of the fellers with the 'experience' you seek probably gonna have a hard time 'typing' you a reply with their stubbs, if they can even see the screen at all . . .

The title of the posting:
"Anyone with experience blending powders for specific results? "
I do not blend powders, Do not recomend that anyone else do it either.
If more speed is wanted get a larger cased cartridge and longer barrel.
] Jeh7mmmag, and the the others that have responded with some good advice. My advice would be to follow it.

Another vote from the: "Never do this" or the "not worth blowing up" crowd.
Bad idea. Don't do it.

No use blending....just fill the case up with Bullseye.
I can be outlandish too.

At least I caught it before I blew something up, poured it in a pile and lit it up, kinda cool to watch. matt The same thing happened to me one time because I let my loading bench get cluttered. I adopted a similar rule. I also adopted the practice of leaving the container I am using on the bench and open so that there is no question which powder is in the hopper. I do NOT leave powder in the hopper overnight, ever.
