6.5 PRC 22" Barrel Vel

Has anyone working with the 6.5 PRC Chronographed out of a 22" barrel?
I ran a velocity estimator and it showed it losing only 20-30 fps from 24-22". Does that sound right?

The only way to know for sure is shoot it and compare the results. No 2 barrels shoot the same even coming off the same machine and production line. I have 1 barrel (223R) that consistently give me 100 fps more over my others with the same length. Some shoot slower.

As Blue mentioned no two barrels shoot exactly the same the only way you could get an exact answer would be to take a 24" barrel, chrono it then cut it off 2" and chrono it again using the same ammo. Your 20-30 fps is probably not far off all things being equal.
