I prefer drill prime too.

The reason you stay away from the starter is it may take hundreds of revolutions of the engine to build oil pressure with the starter. In the meantime your bearings recieved no oil. Nothing up to the rockers yet either, which also means no drainback. So the camshaft lobes are dry too.

Now even with the perfect prime. The cylinder walls are not all lubed and the connecting rod small end (wrist pins)are still not lubed.
This is why after priming, it is essential to get the engine to fire up on the first hit.

Have the distributor pointed correctly and the carburetor bowls filled.
