realistic velocity out of 16" barrels

[subhuman]

I was wondering if anything of ya'll had chronoed some of the factory 120-129 grain loads out of the 16" Ruger Ranch or Howa rifles, my Hornady Black and PPU 120 HPBT boxes are both claiming 2600 fps+ on the box but I figure that was from a 22 or 24" barrel and I was wondering what ya'll were getting in the real world out of the shorter carbine length guns
