What speeds should you expect from a 20" shooting the 143 handloaded?

I would want 2950 or more otherwise its not worth the extra powder my Creedmoor and my old .260 are pushing them at 2810fps from 20" and 18" barrels.
So to warrant the extra powder you would like to think 2950-3000 shouldn't be too much to ask.
