Setback Problem

[SC_Dave]

That's pretty short for a RN, so I don't think that was part of it, although it can only help having more bullet in the case. Adjusting the sizer down probably did the trick.

Did you play with the amount of flare? Cut it down any?

Yes I did. I took all of the flare out and then dialed it back in gradually until the bullet would stay in the case. I forgot I did that too. I didn't measure the before and after but I'm sure that helped too.

Also, I'm probably wrong on the 1.100. I was back upstairs at that point and was going by memory which does not serve me as well as it use too.

The sizing die should be able to be adjusted down far enough to 'cam over' at the top and if it can't, perhaps you have the wrong shell holder that isn't thick enough? Something doesn't sound right there.

Being as the 9mm P is a tapered case, you really do need (most of the time) to fully size them which means the shell holder is firmly pressed against the bottom of the die. Any less than this and the tapered die isn't going to push the case mouth and part of the case that holds the bullet down far enough. But seriously...check into why the die doesn't have enough adjustment to 'cam over' without running out of locking threads.

Here are a few things that may be contributing and if you know something I'm missing or should do different let me know.

I don't mean to over simplify this or make it sound adolescent.

1. It's and RCBS die.
2. It's on a Hornady Lock n Load AP Progressive press.
3. The LnL press uses die bushings which eats up a little of your thread engagement area.
4. If I cam-over too much it flexes the shell plate and throws off cartridges that are in other stations at the same time. (hope this makes sense) Which I would think is a pitfall of any progressive press.

So considering all of this I nearly ran out of threads by the time I got the die down far enough to fully size the case. It's barely catching.

You can't push factory bullets deeper into cases because most factory ammo uses asphalt to prevent bullet setback, rather than a taper crimp.

???? I'm at a complete loss on this one. Asphalt ?

Do not cam over on a tungsten carbide die. It may crack the sizing ring. " Asphalt " The military puts a sealer on some of there ammo. It keeps water from getting past the bullet & brass. Not something thats normally done by reloaders.

Is this done by companies for commercial sales like Hornady, Remington and Federal etc?

Pulling factory ammo is the only way to know if " Asphalt " was used. I just pulled some 5.56, some crimped primer rounds had, some uncrimped primer rounds, none. The Win 45 acp 230 gr ball, none. .17 HMR Rimfire , none. Never seen it on 243 Win ammo loaded by Win. or Rem. See post #10 http://www.thehighroad.org/showthread.php?t=801969 Bullet Sealant .

Ok, thank you for that info. I appreciate you going to the effort to share that.

In the vane of 9mm commercial ammo we have discussed here have you ever experienced any?

Dont remember pulling any 9mm. Never loaded any 9mm . Did buy Federal American Eagle by the case to test fire used police S&W 659's . I would guess 9mm military has sealer and commercial doesnt??

OK, thanks very much for the information. So basically it's a sealer?

Yes, for water proofing. http://slideplayer.com/slide/7290607/
