I have no idea why they would recommend a PRB for that twist. 1:48 is about as fast as you really want to go with a round ball. Its a decent twist for conicals and ball but not ideal for either. most round ball twists run from 1:60-1:72. I would imagine accuracy would be pretty bad unless you kept the powder charge really low. Too low for any practical application.
