Instructions are not very good - Hornady Cam Lock Bullet Puller

Maybe I just didn’t understand the instructions. This thing works great but the only way I could get it to work Is by feel. Pulled 45 rounds of 5.56 factory ammo that wouldn’t drop in my case gauge. I didn’t even want to attempt it with my inertia puller. I kind of expected to run the ram on my press all the way to the top, cam the puller over, and drop the ram to pull the bullet. Maybe with pistol bullets that will work but with rifle bullets you have to kind of feel the bullet enter the collet, cam it over and then drop the ram, about half of a stroke or maybe more. Puller works great after I got it figured out. Would have given it 5 stars except for the instructions.
Pulled bullets were 55 gr. FMJ’s and most of them you couildn’t even find a mark on them to tell that they were pulled.
