Wheel guns I used a slow burning powder like 296 Ball Powder. I know, it's a bit dirty but I had a long barrel and the gap between the cylinder and the throat of the barrel allows a lot of gas to escape.
With that powder I was still making pressure the full travel length of the barrel.
Never had the .454 thunder Jet. A friend of mine did.
I've forgotten what I used in the .222 contender. They were a closed chamber firearm so powder had to be faster than the revolvers.
The best powder there is for FULL power loads in magnum handguns(.45mag, .454, .44, ect)is H110 from Hodgdon. 296 is very close(a bit hotter and slightly dirtier. 2400 is ok but is REALLY dirty and the mv is higher (usally)with the other two. If you reload for magnum autos like the Eagle the best powder is Accurate #9...good velocity and very clean. Just be VERY careful to follow the loading manuals EXACTLY....otherwise you may damage the gun AND the shooter.
There are also a lot of variables, What brass you are using, primer, bullet brand and wieght, and different guns like different combonations of all this stuff as well. I don't think there is an absolute best powder/bullet/brass ect. ect. Combo, Just takes alittle trial and error to find what shoots best in your particular gun. I've used H110 before as well...Just never got around to buying anymore. I got a bunch of 2400 really cheap, So thats what I have been using. And who wants to send me there unwanted Desert Eagle .50 AE???? I can dream......
