I agree with Michael, unless there is a reason for a very tight cloth, 30 is more than generally recommended. What is the weave structure? Unless it is satin, 24 to 26 would be more the range used for 20/2 silk.
Some silks - spun very loosely - will develop little handcuffs with their neighbours. Gently, slowly, remove them and beam.
Next time wind the warp with two threads at a time - that sometimes helps things go more smoothly. Keep the warp under tension as much as possible - no winding on without tension. I hang a water bottle off the warp chain to provide consistent tension for beaming.
Sigrid Piroch said the same of the Slovac weavers - when cotton became available, they stopped using linen so much because it was easier to work with and cheaper than linen. Interesting how things change over time. :)
