Just in case the Hornady reference does not convince the doubters, I knew I had read this in more than one place. Google found a reference to the Speer manual, so I found this in my Speer Reloading Manual #13, page 137, the intro to the .223 cartridge data:
"Most .22 caliber centerfire rifle bullets are of light construction for varmint hunting. When fired at 3,200 fps in a 1-in-7 twist rifle, the bullet is rotating at over 300,000 rpm when it leaves the muzzle. This rotation is more than most varmint bullets can withstand so they are literally ripped apart as they leave the barrel.
If you have a rifle with the faster 1-in-7 twist, you should limit the muzzle velocity of sporting type bullets to 2,800 fps."
It goes on to recommend other bullet styles and weights they offer iin .224" that are suitable for faster velocities (heavier jackets). Of course this has to be taken into context of the types of bullets they make, and does not apply to all varmint bullets by all manufacturers.
I have zero experience with thin jacket varmint bullets and am only passing on advice I received from two bullet manufacturers. I suppose they may be faking the data and just read it on the interWebz themselves, but I suspect they have more insight into how their bullets perform than that.
