I want to drill some 308 and 30-06 shell casings I've got. I'm assuming that the Beall Collet chuck is my best bet. So I emailed Charles at Woodchips asking which size I needed....no answer...maybe he's having email issues. Lord knows I do! Anyway my question is this: Are the sizes he lists for his collets the smallest they will close ....or it it the largest they will hold. The 308's I want to drill measure .470 just under 1/2 inch. Do I need a 1/2 collet or the next size up I think it is a 9/16. Or do I need the one under the half, the 7/16
