    I've seen that article about a year or so ago, it just gives you more respect for those old loadings that is conciddered obsolete by todays standards.

    Pretty neat test, BUT unless he went and had custom 1" boards milled, his boards were only 3/4" thick. (1 x 4 is really .75 x 3.5) So, the .31 penetrated a bit beyond 1.5", the .36 went a bit beyond 2.15", the .44 Army went through 3" of pine, and the Russian or S&W round went through 3.75" etc etc.

    Not that I'd refute BP revolvers would do the job, and mine is amazingly accurate..., just his "test" was a bit scewed.

    Hmm, I wonder if there's a ballistic gelatin test around the net somewhere... *Googling*

    Rough sawn 1" pine lumber is easy to get. Any sawmill produces it daily. Custom work is not necessary.

    <<"Butler says the U.S. Army's 1874 Ordnance Manual listed ballistics for the .45 S&W cartridge as fired in the Colt Single Action Army revolver--which, incidentally, had just been adopted for cavalry service. That manual said the load launched a 230 grain bullet from a 7.5" barrel at 730 fps,">>

    What did they measure that velocity with back then, a pocket watch?

    Most likely with a ballistic pendulum, which was invented in 1742. There were other methods too: shooting through rotating paper disks, or through fine wire meshes that start and stop an electromechanical clock. See http://en.wikipedia.org/wiki/Ballistic_pendulum .
