First .223 reloads - Sucess and Major FAIL
Dan W:
The sizer ball resizes the neck when it pulls back out of the case.
The die squeezes the neck down on the downstroke to about .219-.220" then in the upstroke the ball is pulled back through to set the final neck size of .221-.222"
The problem could be that the sizer ball is too big and leaves the neck dimension .224" or the same size as the bullet...result? no tension to hold the bullet in place.
This is not an adjustable thing. It is either right or it is wrong. I would measure a few necks after the full length resize operation.
If they are too big (.224") then your sizer ball is defective ( too large ) If it is just a bit too big they can be polished down to the correct size.
As you can see .001" can be the difference between go and no go
Dan W:
I would also measure some of your bullets to make sure they are not undersized

You cannot compensate for bad neck sizing by crimping, you are just asking for MAJOR trouble doing so.
Measure your bullets with a GOOD digital micrometer that measures to the thousandths (.000) they should be .224
If they are the you need to take your sizing die apart and measure the expander ball and make sure it is .223 or a little less.
The way the die works when you resize / decap the brass is this:
As the case is pushed into the die the expander ball passes through the case mouth, beyond the neck and into the case - the neck is then compressed down to about .220 ID. As the case is being pulled out of the die the expander ball passes through the neck and will expand it to about .221 - .223.
I have to ask, when you resized your cases did you make sure to lube the inside of the case neck? If not the extra drag created by the expander ball in a "dry" case neck can actually open the necks too much.

So, I did measure the Nosler bullets i'm using. I looked at 20 and every one came out at 0.221. I'll have to open other boxes after work since i ordered 1000 of these. Yes, i did lube the interior of the case necks too. I used Hornady One Shot Case lube to spray them all before I dumped them into the case feeder.

Here is the pics of the rounds that failed. Notice one of them is NOT a reloaded round.
