I sent Wolf a e-mail last week inquiring to the release date of the 75grn .223 Wolf Gold and the 6.5 Grendel. I received the response today. The inquiry was sparked by both being listed on their 2006 catalog.

They are testing our new 75gr 223 right now. We should have it around the end of June. We will be producing the 6.5 Grendel this spring. Thank you for your inquiry and interest in WOLF Performance Ammunition.
