Look at it another way;

Suppose someone shoots matches that require a certain round.

They shoot that match at 200 yards. The required round is capable of excellent accuracy at reduced velocity. Plus there is less recoil making it easier on the shooter.

The example I'm using is CMP GSM matches, fired at 100 or 200 yards max. The ammo required has to be the ammo designed for that rifle which can't be modified for the match. There is no reason to load the round to 2700 feet per second if it develops excellent accuracy at 2200 ft per second.

Also reduced loads cost less to load.

Another example is high power rifle matches. 200, 300, 600 and even 1000 yards. Most people don't have access to such ranges for practice. So he gets reduce targets and practice at 100 yards. Why go to the expense of making match ammo to shoot 1000 when cheaper, reduced velocity ammo will work quite well for 100 yard practice. Easier on the shooter, rifle and pocket book.

There are many reasons for reduced loads.
