Zach,Looks like IMR might have some load workup's on their website.
Might have to try some .308 loads out.
Zach,
I have no idea if IMR has any on their website, but http://www.hodgdonreloading.com/ does. They have .308 loads for 4166 with many traditional slugs.
Pretty sure they are owned by the same folks now.The IMR site redirects you to the Hodgdon Reloading site, but yeah lots of good data out there.
