Neck tension, how much is too much?

I ended up making some small changes to a load I was working on, that involved me having to use an RCBS kinetic puller for the first time (X3).
I didn't have any expectations to what I was in store for when I dropped a bullet in it, but was a bit concerned with the outcome.
I brought the hammer in to my mudroom, and gave it a few taps, no luck. I ended up having to BEAT that thing off poured concrete about 40 times before the bullet came out. Felt more like a prison break than the delicate finesse I have been developing as I learn to reload.
Caliber is .220 Swift, RCBS dies.
This is one topic I am not finding a lot of information on through Google searches.


Also, while I have your attention, I want to thank everyone for their help as I get deeper in to this hobby. The reading of others questions, the answers to my own, and also some very in depth help via PMs. It is good to have a collective knowledge to fall back on.
For those of you who say you have been doing this for 20+ years, you have my upmost respect, that puts you before the internet for knowledge. I could not imagine the mess I would be making (or dead) if I wasn't reading 5 hours a day on many platforms.
Also, in CGN, this is one of the only sub forums where there seems to be a constant respect, that says a lot too.
 
Long story short , the kinetic pullers so just that use kinetic energy to pull the bullet (aka the momentum of your swing ). A light small caliber bullet will be much harder to get out then a heavy big caliber bullet . It's probably nothing you've done in your reloading process , but I gave up on that style of puller a long time ago for this very reason
 
As daft as it sounds, poured concrete isn't as good a hard thing as a plain rock. Not as dense(wood is hopeless). A hunk of granite works well.
It's actually the sudden stop that causes the bullet to come out. That Newton guy's Objects in Motion law.
 
I am guilty of using a kinetic puller, have planned to upgrade just haven't. I pound mine on the base section of my 6 inch vise, not the jaw section. As previously mentioned, a lighter bullet does not have inertia to over come the grip of the neck. I am curious as to what your neck tension is? In my 6mm br the loaded round neck diameter is .002 larger than the neck of a resized case. I have read that this is a good number to have. If yours is markedly different, it may be something to look at.
 
I have a couple of the collet type pullers that go into your press, clamp onto the bullet and then pull it out as you draw the ram down. The down side is you need a dozen or so collets to cover most calibers.
 
I use a kinetic with an ear plug in the bottom.

I whack it on a small sledge hammer I keep beside my bench. Only takes 2 or 3 hits most times and the ear plug prevents damage to the bullet.

Cheap.
 
I haven't gone to the collet style puller because I reload for too many cartridges and it is rare that I pull bullets. There is a different style of puller and it looks like a large nutcracker, not sure of where to get it

Edit; Found it, its called the Grip N Pull
