So, I have received and used the 308, 358/355 and 22 collets for the Hornady cam lock puller.
It works well when doing many bullets/cartridges of the same size, but you have to constantly tinker with it if the bullet/cartridge is changing. I had some random 9mm and 9mm Corto that I had to pull bullets, and I quickly learned to do all of the same ones together. Probably should have realized that first, but I didn't. Some of the bullets got marks/indents on them depending on how deep/tight they were seated. They were all jacketed/plated bullets, so no straight lead.
Rifle is a lot easier than pistol since you have a lot more room to grip the bullet. One some of the deep seated 9mm that I was pulling, I only had a small amount to grasp. Still worked though.
I am not seeing any of the damage that the video linked showed.
