Of course, the .30-06 set them first. No other cartridge was used for virtually 100% of the NRA courses of fire from 1906 to 1935. Since then, they've all fallen as other cartridges were allowed.
First ones to fall in shoulder fired rifle matches were the long range ones trounced in 1935 by the .300 H&H Mag. Others further trounced at long range up to the present were done so by other cartridges starting with other 30 caliber magnums in the late 1950's. Starting in 1963, all the others were trounced by the .308 Win. in the next couple of years. The .308's superior accuracy is the reason the NRA reduced the target scoring ring diameters; too many unbreakable ties were fired.
If you add up all the newer courses of fire in competition added since 1963 and check the record scores fired in each with all allowed cartridges, you'll see the .308 has set more records than any of the others to date. But the 22, 24 and 26 caliber ones have began eating away at the .308's record for a few years. Only at the longest ranges does the .308 remain the cartridge of choice for most shoulder fired matches.
