My point was to used published data tested with pressure equipment from the same source as it gives the most like for like comparison.
Yes the creedmoor can be hot rodded further, my old 24” had 139 scenars skipping along at 2860 FPS over a stout load of RS60. But equally you will then get claims from people who ‘load 6.5x55 to modern pressures’ of equally high velocities. By your own admission your kid is a little hot.
You may recall the guy on UKV (as you’re on there) a few years back when creedmoor was becoming popular who claimed something like 3000 FPS with a 140 and no pressure signs. After much bickering he refused to give his load until he had run rounds through the proof house to prove they were under pressure, he submitted and then all went quiet the only reasonable assumption was his rounds came back well over.
Hence the use of published data for comparison because none of us really know the pressure of our loads!
