Dacron filler?

What is dacron filler and where may I find it. I intend to load some cast bullets in 30-30W. The charge I'm going for is 7-11grs. of Unique. That seems like I'll have a lot of empty case. Some say it'll work just fine but I think it may work better with some filler.

I never used it with Unique in any case with any charge - no need IMHO. If you are not using a gas checked bullet (again no need in a 30-30 with a 170 gr bullet) then make sure the base is free from bullet lube. That includes the side base if running a gas checked bullet barefoot.
added The Lyman 49th E. 311041 170 gr Unique start 7 gr 1240 fps 21,600 CUP Max 10.6 gr 1555 fps 35,500 CUP
They say their most accurate load was IMR-4198 18.0 gr 1602 fps 23,200 CUP. I would consider a Kapok filler for this load.
I've used Dacron, over light loads of fast burning pistol powder, many times. For reduced loads in large capacity rifle cases.
There is one thing to consider though. Some folks maintain that this practice would cause "Rings" in the chamber. Although it never happened to me. You might consider, loading Cream of Wheat or Cornmeal. Between the Dacron and base of the bullet. To prevent possible ringing of the chamber.
I don't think you need it.
Okay. Thanks guys. So Rufe, what you're saying is dacron on top of the powder the cornmeal on top of that? Do I have that right?
I just used Dacron. In large capacity BP cartridges. 30-30 is much smaller internally. Because of this it might work without any filler, between the powder and base of bullet.
I would make up some test loads. Say 10 each, with and without Dacron. See which gives you better accuracy. To me, it seemed you almost could see the difference. Between the load where the Dacron held the powder in place on top of the primer. And the load with powder loose in the case.
Burning rate of the powder, also might be a factor? Some pistol powders, have a substantial amount of Nitro as a component. Using those might be a factor, vis a vis slower burning powders. You could get away , with out anything holding the powder in direct contact with the primer.
Look at load data for TrailBoss powder, it was made for what you want to do.
I'm using winchester l-r primers which are hot for a standard primers. I just finished loading 20 w/o filler. I've got 20 more cases ready to go when I get some filler. I went with 7grs of Unique. I sorta wished I went with 9 or 10 gr.
A ball of Dacron the size of a quarter. Than use a 1/4 inch wooden dowel, to compress it on the powder. To keep the powder from shifting. Around the case, so the powder is sitting on the primer.
