Yes it helped.

Sorry it's metal not plastic.

Thanks Matt, did the same trick with filling up the dog space with a piece of coke can, coke zero actually

It helped indeed but it didn't take away all the thunking. I guess the thunking is now 50% less and I presume the rest is

due to the play in the bearings.

thanks Matt for the tip.

@probike the swager is not the problem, the play in the bearings is. Brian if you're reading this, can you step in please?

Does Dillon know of this problem?

[1050 troubble with thunking]

pm'd him too, no reply thus far

[1050 troubble with thunking]

I think he was asking for the specs of the replacement bearings Mythos used.

ok, didn't get that, but that's what I would like to know too

[1050 troubble with thunking]

was mentioned in first post Steve, 3 BH-1610 Roller Bearings Dillon part nr #11008 see Super 1050 Lower Machine Assembly drawing on Dillonprecision.com

there's an awful lot of play in the bearings of my almost new 1050. I can literally move

the handle sideways and see and feel the play. This is absolutely what causes the thunking.

If anybody from Dillon is reading this, can they comment please? Is the play meant to be there?

Is there a factory solution? Do we have to solve it ourselves as Mythos did?

[1050 troubble with thunking]

there's a lot of play in the bearings. Does Dillon offer better/upsized bearings?

If not then I've got to go for the same solution as Mythos.

[1050 troubble with thunking]

A thump when the case is pulled out of the sizing die is normal. Not normal if it causing powder to spill. I'm guessing you need a more solid bench or more lube on the case (if straight wall).

Is it really normal and shouldn't I worry? Mine doesn't spill powder.

[1050 troubble with thunking]

use dillon lube and I bet it goes away....

No sorry, it doesn't.

Same problem with my 1050, thunking/clunking on the sizing and swaging station on the upward stroke,

when the brass pops out of the die. There's a lot of play in the bearings which

seems to cause the clunking/thunking. My 1050 hasn't produced more than 4000 rounds.

And a tight cap doesn't help.
