Like basic highschool physics that says you cant get something for nothing
Every action has an equal and opposite action

only way to make the bullet go faster is higher pressure.
Not entirely correct - lower pressure applied more evenly would work for faster bullets. The problem with single-chamber chemical propellant guns is the pressure spikes and drops rapidly. If you could arrange the propellant such that it maintained pressure, the bullet would go faster. Think of pushing a child on a swing: a short forceful push gets no better results than a longer less forceful push. Or one could arrange for more chambers, a lighter propellant gas, etc. Google "harp" and "gerald bull".
Nope. If a short full-force push gets the same speed as a longer less-forceful push (which is what I said)... then a longer full-force push will get you even more speed. Have a look at the pressure curve they're promoting- notice that the pressure is noticeably higher on the tail (past-peak) part of the curve.in the same paragraph you make a point and then disprove it
To some extend it is, but slower-burning powders require longer barrels to work (and there are limits imposed by thermodynamics / friction). For example, I can reload 9mm with HS-9, a relatively slow pistol powder, and get great results in a pistol-calibre carbine with a 16" barrel. Much better than would be possible with, say, Clays. The same load in a 4.25" barrel will not be much if any better than the Clays load.I think I get your point acrashb, but isn't that what we do by using slower burning powders when we reload?
they claim that they are not using one powder but a blend that the reciepe is changed for each specfic load, the stuff that I've read says they are blending and crushing different powders to acheive a more rounded pressure curve than a quick spike, Blah Blah Blah..... If handloaders can't get the powder or there exact receipe it's not going to stop us from handloading, they seem to think eveyone will stop handloading and buy superformance because the results (in thier opinion) are better than what an average hanloader can expect to acheive. LOL.
