IMHO, trim them to 1.704 and see if the bolt will close. If it does, you're good to go and the shrinkage, while not as bad as Hornady 450b brass, should drop them right into spec after the first shot. If the bolt won't close, take .001 off and repeat until they do fit. Important: After you cut them down initially, close to the 1.704, resize them in the 450b die before you do your final trim them to 1.704. I say that because if the .284 chamber they were shot in is a loose chamber, resizing them will make them grow a little longer and if you did the 1.704 trim beforehand, they might be longer than that afterward.
