Bullet Seating Issue

[devildog999]

Was reloading some 30-06 tonight and with about half the bullets I tried to seat, they were easily pulled out after seating. I only neck sized due to these being for a bolt action and I could easily tell before even seating if the case was going to be an issue. With a little finger pressure, a bad casing would accept the round.

Any ideas?

What dies?

Is it likely when I was chaffering the inside of the case mouth that I opened it just enough to cause this problem?

What clued you in that some cases would be "bad"? What brand and model bullets?

You're probably not sizing the neck enough. Try screwing the die down 1/4 of a turn.

++++1, I had the same issue, I kept turing the neck die down until I got the pressure I wanted.

After several cases had this issue, I decided to try and see if the cases were too loose before I even tried seating. Before I would seat, I would take a bullet and see if I could easily push it into the mouth. Half my cases easily accepted the round where as the other ones wouldn't take it and seated properly. I checked the measurement of the mouth on one that was taking it too easily and one that needed the die and the difference was .01.






I will resize and see if that works. Appreciate the advice.

You might not be pulling you press handle all the way down consistently. This was my problem when I first started reloading, I hear the primer fall and I guess stop and go up stroke.

I'm having the same problem last night with some range brass in 45 ACP and I'm full sizing the cases. I even ran them through the resizer die twice (Hornady Carbide set).
I'm new but the process seems simple enough, supposed to set them up so there is light pressure before it cams over. The Taper crimp die (Redding) isn't putting much of a crimp on these either. I can't pull the bullets out due to the taper (no grip) but they sure press in easy (one slipped inside the case while I was measuring it with calipers.)

I noticed the stamps on all of my problematic cases is the same, guess that's what I get for grabbing range brass. None of my once/twice fired brass has this problem.

That's how I figured out the first one that had the issue, went to measure OAL and it pushed it. Very frustrating to have half your brass do that. At least it should be a fixable issue.

fixable? You mean by throwing the brass and primer in the trash? heh.

Ya, I just sent out and bought a $25 bullet puller to save my $2 worth of Hornady XTP~

I have a fix for you.
I have the same problem, Lee 308 neck sizing die.
The problem is the mandrel is a little too big. What you need is to bring the mandrel diameter down by .0005". Right now it is .3055", you need it to be .3050".
Right now, your neck size is .308" or a little bigger, this mod will bring you down to .3075"
How to: Power drill and 400grit sand paper.
Order an extra Mandrel (#NS2627)from Lee and take that down to .3045" just in case.
It is best to use same Brass brand, with close number of use, different brass have different spring back.
Hope this help.

Problem solved. De primed the problematic casings. Gave the neck sizing die an extra 1/4 turn and didn't have a single issue with any of the 39 casings that needed to be re done. Thanks for the help guys. Lost some fresh primers but at least I didn't lose the brass.

Not sure why you had to deprime? I didn't when I needed to resize?

Ah, the decapping pin can be removed in most dies. I'm not familiar with the Lee but it comes out pretty easily on the RCBS dies I use.
