Just curious is there a way to make the 9mm hold more powder? In reality the whole point is to be able to shoot the same ammunition in rifle, sub mg and pistol.
What started me thinking about this is the idea of finding the correct powder and the exact amount of that powder to cause the bullet to exit the barrel just as the bullet exits the barrel. Any more would be waste and too little would cause drag on the bullet for a portion of the barrel. Thus, a 9mm pistol load optimized for a 4" barrel would cause the same bullet to be exposed to 12" of barrel drag in a 16" barrel, AND the vice versa would be a lot of powder wasted. I have seen, in one of my reloading manuals, data for a RIFLE .44 mag load and it warns not to use the load in pistols - why not the same in 9mm, or .357 mag? I acknowledge that there would be a few idiots that would try the rifle load in their pistols, if it were available.
Again, just curious......
