I'm looking for good cast bullet loads for a 308 Win. that would still feed in a M1-A1. Tried some 180gr. loads today using 20gr. IMR4227 that showed good accuracey but only about half would cycle properly in the semi-auto.

NB,
Try the cast boolit loaders forum. They know their stuff and are a nice bunch of people.
They are moving to a new sight April 4th. If I knew how to cut and paste and all of the computer stuff I would give you the link but I'm an idiot so you will have to find it like I did.

Here ya' go:

Cast Boolitts at Aimoo

Nice folks too (even the curmudgeonly ones!)
