centifuge as a reloading tool?

Years ago when Hornady came out with their "Light Magnum"ammo line I read a test article in a gun rag.I don't recal the rag or the author.Said author tested the ammo -it did as the manufacturer claimed.He pulled some bullets & found a suprise.He couldn't identify the powder & when he tried to put it back it overflowed the case.
Using a press doesn't make sense but I was wondering if a centrifuge might align the powder grains such that "extra"might be fit in.I DO realize that powder selection would be critical for this.I'm just wondering if anyone has tried something like this or had a similar idea?
thanks,jeffw
 
My vote is for multiple compressions, as in fill the case full and use a caliber sized pin to compress the powder as much as possible and then put the rest in after that. It is voodoo loading that few venture into but you can get a LOT more powder in a case than you think. Clark posts on here and has used this technique quite a bit, you can do a search on his username and see some of the charge weights he has used to get an idea of the potential of multiple compressions. I think they are using drop tubes and multiple compressions of the powder. I also think that the powder is specially formulated for this use, and attempted duplication outside of a ballistics lab is very dangerous.
 
Black powder shooters discovered long ago that by using an extended drop tube with the smallest opening that the powder would flow through that you could get more powder into the case.

This also works with smokless powders too.
 
Does anyone know the coefficient of thermal expansion for the powder used, or for any powder? It may be as simple as keeping the powder as cold as practicable until the bullet is seated.
 
The drop tube trick is a good one.

It's how I load my black powder .45-70 rounds. I even converted an old aluminum ski pole into a long drop tube. After I throw a FFg charge into a .45-70 case through the ski pole drop tube, I can take the filled case, tip it upside down, and the black powder will not come out.

I've been toying with the idea of using the same technique for my hotrod 6.5-06 loads lately, since 59.0gr of H4831SC is halfway up the case neck, and the long 6.5mm 120gr bullets seriously compress that load. With a drop tube, it may reduce the powder compression a good bit, or allow another grain or two of powder to fit in the case. Pressure signs being observed, of course. ;)
