Since you did not understand the inertia bullet puller at first sight your understanding of loading die function is also suspect. Don't blame RCBS if you have having problems with their dies. It sounds like you need a lot more experience with all things related to handloading.
Just remember that when you pull some mickey mouse .22 caliber or 6mm bullet you need extra high velocity with the hammer to pull those dinky bullets because the weigh very little.
A 500 grain 45 caliber rifle bullet takes nothing to pull- just a light snap of the wrist.
That's strange, RCBS contacted me, apologized for the defective die and replaced it for free. I discussed the steps I'd taken and they confirmed that everything I was doing was correct. Next time you read a post and decide that some condescending narrow-minded response is appropriate, think again. I'm quite sure that you've never purchased an item or received something that lacks directions and is a bit confusing. Your arrogance is sickening, I pity your wife.
