It's not just about stringing shots due to the barrel's reaction to heat- it's also about minimizing throat erosion due to that heat, and that's critical on a real barrel burner like the .22-250 which is usually only good for 1000 rounds or so.
When practicing, I probably go to conservative, i don't hesitate to give 10 min between shots.. heck alot of times by the time I'm ready to let next one go, the range officer gives the 2 minute warning
