Welchers in Tacoma is probably your best bet. The Oly area is kind of a black hole for reloaders anymore.

The .22-250 also shoots well with a lot of your other .308 powders. The intersting thing about this powder shortage is that I've ended trying a lot of powders I wouldn't have normally used.

4895 and 4064 seem to be readily available if you can't get your hands on Varget. WIN 748 too. That should at least get you going. If you need some brass, let me know. I have a ton and I am just down the road from the Oly/Tumwater area.
