While this is a little off topic for the "Hunting" forum, hopefully, because it's shooting related, it'll be acceptable.
The other ".30-06 100 yr. Anniversary" topic is fun because it has to do with our most popular Sporting cartridge for hunting, the .30-'06.
And as has frequently been the case with popular Sporting/Hunting cartridges (.45-70, .30-40 Krag, .30-06, .308 Win/7.62 NATO, and .223 Rem/5.56 NATO), the '06 was first a U.S. Military round, later adopted for hunting.
It first appeared in the 1903 Springfield bolt action rifle, then later, in the 1917 Enfield, and finally in the M1 Garand rifle that was the main battle rifle for WW-II as well as Korea and wasn't replaced until 1957 when the "Improved Garand" 7.62 NATO M14 Rifle appeared.
So, many of us know this...and maybe now, those who didn't, do.
But did you know that ORIGINALLY the Garand Rifle WASN'T a .30-06?!! :shocked:
Originally it was a .270!
It fired a shorter (more similar to a 7mm-08) round that was called the ".276 Garand"!
In my collection of Odds 'n Ends Cartridges, I have one. It's marked "FA31" (Frankford Arsenal 1931). Kinda looks like a miniture .30-06! :grin:
The Army was skeptical about its performance and had tests performed. The .276 Garand passed, with flying colors!
But later, it was shot down by Gen. McArthur, who insisted that the rifle be built in .30-06!
So, that's what happened...John Garand went back to the drawing board and redesigned certain dimensions and changed various components to make it compatible with the already existing standardized military cartridge.
What he came up with was one of the best battle rifles ever built.
Don't be surprised if someday you see a similar .270 military cartridge adopted.
John Garand was just way ahead of his time!
