I chrono'ed a 270 WSM for a guy at the range a few weeks ago with 150 grain Winchester factory loads at 3226 FPS
Wow!!
I had heard that some of the factory stuff was loaded hot, but that's screamin'. The best I have seen in mine is about 3050 with 150gr Partitions over 68gr of Magpro. Any hotter and the bolt gets heavy. The fastest I have pushed 140s is the mid 3100s.
In fact 3226 is, according to the loading manuals, fast for the 270 Roy.
This being said, I would call 3226fps an anomaly for comparison purposes.
