Then if all chain you can usually get away with a lessor scope than if line, especially if you have a huge anchor

Are you anchoring overnight? Just during day when you are at boat and can keep watch? In calm conditions? Or storms?

Scope could be anywhere from 3 to 5 to 7.

250' is not enough for 50' depth if you are doing 5 scope. You would need 280 feet I think? 50 + 6 = 56 * 5 = 280 plus some extra to get from pulpit to windlass to anchor locker where the end gets tied, thats another 10', so you'd need 290 on the ST44 for a 5 scope and 50 feet of water.
Those from the East Coast often anchor in 10' water. There, anchoring with 5 x depth is not excessive.

Here in SW BC, and in PNW, where our tidal range is above that 10', it is exceptionally rare to anchor in water as shallow as 10' at low tide. Here though, anchoring with more than 3 x depth at high water is rare. In my experience, scope of more than 3x high water depth occurs only when the wind is forecast to pick up and there is swinging room. With good planning, that combination doesn't occur often.
For most conditions, 250' of chain is rarely all going to be out. If you back it up with 200' of rope, you will have more than most.
