^^ this data shows 1890 fps... but its not the ammo the OP is using.
if this isnt the ammo you're using, just know its... well... probably not what you need.
the only way to truly have accurate data is using a chrono.
part of the issue is... several retailers for the armscor 147 you're asking about list different velocity's

^^^ shows 1800 fps
https://www.targetbarn.com/armscor-300-aac-blackout-ammunition-20-rounds-of-147-grain-fmj.php
^^^ shows 1826 fps
so which piece of data is accurate? who tested it ? armscor doenst have it listed on their website that i can find.
will 26 fps make a huge difference? depends on the distance. will 64 fps make a huge difference? again - depends on the distance, but more than the 26 fps will.
