I have all the respect in the world for Rocky's expertise. That being said, I have compared Browning BAR's in 25-06 and 280 to bolt guns by shooting the same the loads side by side over a chrony.
Chrony said the BAR was shooting the same loads ~ 200 fps slower.
I believe Browning has publicly admitted the same.
Of course the 200 fps only matters to the chrony. Neither the operator nor the intended critter will notice a practical difference without reading the chrony.
