I got a Frankford Arsenal kinetic/hammer bullet puller as part of my reloading set-up, most of which I bought used (at a great low overall cost).
The last few days I've loaded ammo for one particular .357 revolver using my Lee 4-hole turret with the Lee Pro Auto Disk. I decided to check the powder charge every 5 rounds instead of every 10, as is my usual routine. In this case I'm loading on the low end with jacketed bullets. Unfortunately the case-fill is so low (4.5g of HP38 in a .357 case) that I cannot visually identify an under-charge.
On about the 220th round of this run, I checked the charge and it was very low. The powder dispenser had been sticking a few times in the last 20 rounds, so I decided to be extra careful and pull the previous 2-3 rounds. Low charge on all of them.
I then pulled a round from each of the 4 boxes I'd already loaded. All showed a very low charge. So then I sampled 4 more - same result. By the time I had pulled 25 bullets, I'd found only ONE proper charge.
Now I was baffled - how could my "intensive" quality control (checking every fifth charge) allow so many under-charges ?
This afternoon - after checking various things on the Auto Disk and powder die, per Lee's helpful support team - I decided to pull a few more bullets. On a few of them, I noticed getting a bit of a spray of powder in the face on the last hammer strike. So I swept the floor, and sure enough, though I'd swept it clean just this morning, there was a fair amount of powder where I stopped the push broom.
It seems that, somehow, the FA buller puller is leaking. Everything seems in good working order. I tighten down the collet piece very firmly (sort of required to make it work anyway).
So now it seems that maybe the charges ARE correct after all. Powder leaking from the puller upon disassembly for testing would explain all the apparent under-charges, which otherwise are pretty baffling.
Has anyone heard of this or experienced it? Any suggestions?
Obviously I don't want to pull 190 bullets if I don't have to, so it's important to figure out if the bullet puller is the problem. Not sure how I can do this. Back-up plan would be to buy the RCBS collet puller and a few collets, which has other advantages anyway.
