Geezeer, go to the Lee website and get their lock and stud for their case trimmer. A 30-06 single case trimmer w/holder will run you less than $10. It has a 3/8in button on the bottom of the trimmer. Just attach it to your cordless screw driver and trim till the brass stops coming off and then run the burring tool on the inside and outside. Their tool will cut the squarest mouths in the business and all the exact same length. It's not like you're going to do 500 cases at a time. powdr
