Constitution Arms, the firm behind the Palm Pistol, has developed an interesting multi-projectile .38 Special cartridge called the Palm38 Tri‐Plex.

Three lead bullets, totaling 158 grain, are stacked on top of each other and backed by a copper gas check. The load has been designed to have ultra-low recoil and has a velocity of 658‐678 ft/sec depending on the model of revolver it has been fired from. The maximum range of the round is 10 feet.

The idea behind this round is to increase the frontal surface area of the wound channels, at the expense of penetration.

The concept is similar to the Winchester PDX1 Self Defense .410 Shotshell round that was designed for use in the Taurus Judge line of .410 revolvers. Winchester loads the PDX1 with three copper discs backed by shot pellets.

"The maximum range of the round is 10 feet". Now that requires some explaining.

It probably works best at 10 feet.

Well, after checking out the pfd, and reading that the copper disc's purpose is to "reduce" obturation, and that the case is double cannelured to "captivate" the bullet stack,I'd have to conclude that the person who wrote it is an idiot. Or at least totally ignorant. And that includes the "maximum range" of ten feet.

There is really nothing new about the multiple projectile concept, which never has caught on. But it is re-invented every ten or twenty years.There will be, no doubt, some in the "if it's that expensive (and nickel-plated!), it must be better" crowd, who will eagerly go to the trouble and buy some. But a commercial success it won't be.

And, claiming that the equipment you check your product with is accurate to the .00001th degree, doesn't really imply that your product is, too. Which in this case would really be meaningless. In any case, it's the tolerance you hold your product too, not how accurate your measuring equipment is.

Cheers.

In the early years of the vietnam war, a 308 round was also used, with a 2 projectile load,the second projectile INSIDE the case.Remember the dia vaguely from some old PM ,I think
I wasnt able to read, in the early days of the Viet Nam war, came across this dia/article in my early days of juvenile delinquency
WHY reduce the obturation?
reduce 1 good 158 gr to 3 itsy bitsy pieces of soda bottle velocity...beats me
must be quite the rage with the 'spray and pray' uber metrosexual, mall ninja crowd, eh?
