While you may consider them "fails" because they seem to make no sense, many times if you know the history, it makes perfect sense.
Colt and S&W had a serious rivalry that went on for decades. Neither one would put the other's name on their guns, or ammo, if they could help it.
Got any idea the difference between a .38 S&W Special and a .38 Colt Special? Only the name, and the bullet. .38 Colt was loaded a flat point bullet.
Yeah, and what, praytell, does the "40" stand for? Surely you cannot fit 40 grains of black powder in there.
Yes, you can, and they did. With the original design "balloon head" cases. 40gr of black powder was also the load for the .45 Colt.
You cannot get that much powder in modern solid head brass, though.
And the .32 Colt New Police? .32 Colt (same shell as the S&W) for their New Police revolver. makes sense to me,
Remington and Winchester had generations of competing cartridges. And for a long time, both companies were reluctant to chamber their guns in the other guys calibers. Both eventually did realize that selling a gun, an anyone's caliber did make them money, and today, there is more overlap than there was in the past.
There is one consistent rule when it comes to cartridge naming. The people who invent/make it get to name it. And that's about the ONLY consistent rule.
