So I agree with Sean. Compare apples to apples. Not standard lenght barrels to hunting barrels.
Pat, maybe you should go and look at the Buffalo Bore website before you chime in--velocities were provided for three, four, and five inch barrels. Only one velocity (out of the four compared) was from a six-inch barrel (a point Sean forgot to highlight in his zeal).
The velocities are from "standard lenght [sic] barrels." The six inch Ruger is a standard length (check the Ruger catalog and website). (Besides, all but one of the four velocities were from
shorter barrels.)
The point remains is that the 10mm velocities are from the Glock 20--probably the most
commonly carried 10mm. The velocities from for the .357 Magnum are from
commonly carried .357 revolvers. If ever, there is an
apples to apples comparison this it. These are the
handguns most commonly available and commonly chambered for their respective rounds. It only makes sense to compare velocities with commonly carried handguns--not some artificially created test bed to be "fair." (Or like I used to have to tell my children, "Where is it written that life if fair?")
If you buy a new medium (or "medium/large") 10mm, chances it will be a Glock 20. If you buy a new medium (or "medium/large") .357 Magnum chances are it will be a S&W or Ruger with a four or six inch barrel. If you really want to compare
"apples-to-apples," then you want to use the handguns that are
commonly available and commonly carried, don't you? Very little is "fair" in real life (and particularly when you compare bottom-feeders and revolvers--there really are differences between them, Pat). Frankly, I have no intention of sawing four tenths of inch off the end of my Model 27 to provide a "fair" comparison--if it provides with a four tenths of inch advantage, so be it. If you don't like it, stop whining and go buy a revolver!
Sean's complaints sound more like sour grapes than reasoned objections. I could understand the whining if, for example, the 10mm velocities were from a Glock 29 and the .357 Magnum velocities were from a 686 or GP100, but the G20 is roughly an equivalent handgun to the 686/GP100.
The 10mm in autoloaders is
roughly equivalent to the .357 Magnum in revolvers. What's the problem with that? (Unless are suffering from teminal 10mm oneupsmanship--or, maybe, your nose is bent a little out of shape over something else?) There is certainly no way to build a case that one is superior to the other (and I'm sure not trying to).
