My older RCBS was designed for a person with three hands. Not really true - one knee to keep the ram up, one hand to hold the collet and one to wind the illbred lever at the top to tighten.I use the RCBS collet puller. It may deform the bullets a little but it's a gentle pull to remove the bullet. No primer going off.
Truly, it's been one of the best investments I've ever made. It taught me to get my loads right the first time so I don't have to use the bugger ever.
