Yup...
ES of my 260 Rem load (130 VLD, 43.5 RL17, Lapua brass, WLR) runs between 15-20fps on any given trip, but on different trips to the range I've seen speeds across my ProChrono average a low of 2962 to a high of 3072 for 4 and 5 shot groups.
And actually, the highest velocities were not so much from higher ambient temps; I stupidly left the rounds out in direct sunlight for about an hour before shooting them on a day when it was only about 80°F.
I'm now working up a load with H4350 to see if I can get to 3000fps without being so temp sensitive, but damn if the RL17 hasn't consistently provided great accuracy with Berger 130s.
