The only thing you get from a "higher quality factory round" is consistency. There's alot more to precision loading than just consistency.
Precision reloading cosists of tayloring a load to your rifle. Seating depth, charge weight, case prep, neck tension, specific primers, etc. are all taken into account.
There's no guarantee of accuracy with "higher quality factory" ammo. Will most high-end factory ammo perform well in any given rifle? That depends on your definition of acceptable performance. MOA? Sub MOA? 1/4MOA?
I've had/built rifles that loved Black Hills and Federal Gold Medal Match and hated factory hunting loads. But I've also had/built rifles that did not do well with high-end match-grade ammo but loved Remington Corelokt ($16 per box of 20).
So, to answer your question, you'll only get a significantly better product if your rifle liked the higher end ammo that you're blueprinting to begin with. But even then you'll only have a starting point. You'll still have to determine precise seating depth, case length, and charge weight (assuming you use the same cases and primers). At that point you're practically "reloading" anyway.
