It’s also known as the 7mm International, based on a .300 Savage case slightly modified with a 38 degree shoulder and less case taper. Federal Cartridge Company made a couple runs of this brass totaling a half million cases in the early 1980’s. The “goat” is the official ram target used in metallic silhouette competition, and is the only headstamp used for this case.

The brass was sold through the IHMSA headquarters and came in the 7mm size only. It was supplied as “basic” brass, to be reformed by the shooters into one of 8 silhouette calibers:

.25
6.5mm
.270
7mm
.30
8mm
.338
.35

IHMSA also had Douglas barrels custom chambered in these cartridges for the XP-100 available in a kit form to modify the pistols.

JP–A really minor point, but in the interest of accuracy
the symbol on the IHMSA cases is a Big-Horn Sheep Ram not a Goat.

In a further interest of accuracy, it is a “Borrego”. :) :) :)

Ray–Never heard of a “Borrego”. How is it different from a Ram? Or is that the Spanish word for Ram?

Shooting at metal targets (Silhuetas Metallicas), rather than live animals, originated in Mexico soon after WWII. The first targets were Gallinas, Gualotes, and Borregos. The first competitions in the SW USA were held in the 1960s. It was in Tucson that the fourth animal, the Javelina, was added.

During the early years of competition in the US we referred to the targets by their original Mexican names. I haven’t shot Silhouette recently so I don’t know if that tradition is still alive. 80x80 could better answer that. Even today, the original long range competition is still contested in meters rather than yards.

I’m sure that many of the younger shooters would not know a Borrego from Burro. Just as most of them think that Vietnam was a battle during WW II.

In a still further interest in accuracy, the borrego was originally a sheep. It was an American, Ray Chapman, who made it a Ram for the U.S. version of the game. :) :)

The rifle silhouette competitions still use the Mexican names, while the handgun games use the American ones, and are shot out to 200 meters.
