Maybe everyone could be right:

>>>>So, how many fps do you lose shortening a barrel? It depends on where you started. Going from 26 inches down to 20 inches actually picked up speed, not lost it. In the regular zone, between 20 and 16, the velocity loss could be anything from 12 to 50 fps. When we started down into the SBR zone, we sometimes saw velocity losses of more than 100 fps just from a 1-inch change in length. The short answer to the question of how much velocity do you lose per inch? It depends.<<<<

>>>... traditional rifle cartridges like .30-06 Springfield or .270 Winchester were originally designed around longer barrel lengths, often 22 to 24 inches. Shortening those barrels can reduce velocity noticeably.
But modern cartridge development has changed the game. Many newer cartridges and loads are designed to perform efficiently in shorter barrels, using optimized powders that burn faster and more completely. This allows hunters and shooters to maintain impressive ballistic performance without carrying excessively long rifles.<<<
Barrel Length vs. Velocity - Guns and Ammo
I'm destroying a perfectly good barrel in the name of science. And not just a perfectly good barrel — an expensive one."How much velocity do I lose if I shorten the barrel on my AR?"The answer ranges from

How short do people think a barrel really needs to get to go from 3000 FPS to 2100 FPS (30% reduction)? It isn't anything that doesn't require an ATF tax stamp. Have to get to sub 10"?
Also, lot of people worried about velocity that shoot factory ammo that can easily vary over 100 FPS between lots and they'd never know.
