(Assuming the accuracy is there...)The argument is fair though, the other guys asserted the sentiment that you likely can do anything that the 2550fps load does, with 2500fps just the same. Provided the accuracy is there.
Ive gone down the chase velocity road and what Ive experienced is you wont really gain any ballistics advantage unless you can exceed at least 100fps, preferrably more.
The flatter, faster, more energy advantage downrange doesnt really shine below 100 additional fps.
