I saw an ad for Jamison 250 Savage brass at $69 per 100. The only Jamison brass that I've used is for my 256 Newtons and even though it was a little over $1 per piece, it was worth it to me.

All of the Hornady brass that I've used has been excellent, so if you need 250 Savage brass, you're likely to be pleased with the Hornady quality.
