I have the Hornady bullet puller, Handle? it is referred to a cam operated, problem, I spent more time waiting for parts than than I spent using it. I quit using it and like a miracle it quit needing parts.
I acquired a RCBS puller that uses collets with a ‘T’ handle screw, like magic, all of my bullet pulling problems went away.
The Hornady cam lock puller parts will not fit the RCBS type bullet puller.
