Hi Sacdan, welcome to GotMead!!!
I reckon you want a Sack strength cyser. lol.
You might want to check that hydrometer reading again, most hydrometers will not reach 1.460 - usually they top out at less than 1.200. Was the actual reading 1.146? If so, that is in the right range though I would usually expect with apple juice a gravity from a mixture like yours to hit 1.160 or higher, so again, double check that reading.
If the gravity is 1.146 or higher you are asking an awful lot from the yeast. High gravity starts stress the yeast, increase acetic acid production, and may produce lower levels of alcohol.
Is you goal to make a very high alcohol, somewhat sweet batch of cyser that will take a very long time to integrate?
