Loading 9mm on 1050

Normally runs smooth, noticed small part of shell plate fall out. When I removed plate, almost every location is cracked. I can not come up with a reason or even something that might be set wrong to do it.
Anyone seen anything like this before on a 1050?

Never, I have loaded more rounds on 1050's over the last 20 years than I can remember. Still have two of the old style 1050's. One of those has over 600,000 rds loaded and still works great. :surprise:

Hello: Do you have a power activator on it? It could also be that your swager is setup incorrectly. Thanks, Eric

I'd guess the swage backup/bell tool is a little over adjusted.

Bet that Dillon can tell you what's wrong. I'm sure they have seen it before.

My shellplate started moving vertically more than normal and flexing as the powder drop/expander die was pulled out of the case on the upstroke. The main shaft nut had come loose just enough to allow the shellplate to move upward a bit at the start of the upstroke. This would put pressure I think on the shell plate in the areas where yours seems to have cracked.

No power drive and swager is not even on the machine.

Hello: Expander in station 3? It looks like the plate was forced down by something very hard with no support underneath. Maybe Dillon will chime in and tell use all what happened :cheers: Thanks, Eric

Yep- The swage backup die is set too far down. And without the swager in place to support the underside of the shellplate, The repeated force eventually cracks out the underside of the shellplate exactly as shown in your photograph. time to buy a new shellplate I'm afraid. :ph34r:
Voilą! In view, a humble vaudevillian veteran, cast vicariously as both victim and villain by the vicissitudes of Fate. This visage, no mere veneer of vanity, is it vestige of the vox populi, now vacant, vanished. However, this valorous visitation of a by-gone vexation, stands vivified, and has vowed to vanquish these venal and virulent vermin vanguarding vice and vouchsafing the violently vicious and voracious violation of volition. The only verdict is vengeance; a vendetta, held as a votive, not in vain, for the value and veracity of such shall one day vindicate the vigilant and the virtuous. Verily, this vichyssoise of verbiage veers most verbose so let me simply add that it's my very good honor to meet you, and you may call me V.

Yes, I already spent the $70 on the new shellplate.

But only using an expander...have not had the swage or swage backup in use for at least 3-4 years.
Guess it could have cracked when I was using them, but that was probably 100k rounds ago and would think it had shown up before now.

Hello: I got that one right :cheers: The reason I knew this was I setup the press for 40 and forgot to install the swage rod and could see the plate flex. I then installed the rod and all was fine. The stuff you learn everyday :cheers: Thanks, Eric

Then also be sure the bottom of the decap pin retaining nut is not contacting the bottom of the interior of the case. Back the decap assembly out a few turns, pull the handle down with a case in station 1, then thread the decap assembly down until it stops. Also, inspect the decap pin, make sure a 22 rimfire or or small case is not caught on the end of the decap assembly.

Using a EGW undersize die for decapping which is slip compression retained.

Looks like I must have done it before I removed the swage and backup, wonder why there is a recess in the support platform at that position.

Amazing that it took so long for it to show up.

Thanks all
