You always want to work up loads in your gun to a velocity that gives you best precision and no pressure signs. Since, in real world hunting and, obviously in target shooting, precision of the load (the ability to hit the same place each time) is what allows you to set the sights for accurate shot placement, precision is more important to successful shooting than even a hundred fps one way or the other.
Out of curiosity, why did you want to reproduce the primer crimp? The military added those to prevent machine gun jambs due to a loose primer falling down into the gun mechanism during extraction and causing a jam. Unless you are you shooting a full auto weapon in a combat situation where you don't have time to disassemble it to clear it, crimping just makes the next reload more difficult to do, as you have to remove the crimp to get the next primer in, then form the crimp again. Doing that every time will also shorten brass reloading life considerably.
Regarding warmer load information, you can look at load data from most European sources (Vihtavuori, Norma) as, unlike the U.S., they don't distinguish between the two as far as pressure and velocity goes. Just realize their data will only be for their powders. For U.S. powders, you really need to do the workups in your guns while watching for
pressure signs. Beyond that, we'd need to see the details of what you are loading with (bullet, case, primer) and what kind of gun it's for.
