If you've been shooting a load with a Sierra of the same weight(even a BT or something similar),practicing to distance with that,and know the rifle,you should be done with load development with a Partition in about 10 shots(if that).
That leaves 40 bullets to load for your hunt.
If it takes more than that to get a Partition load,there's something wromg with your rifle. Get it fixed or trip it.
