>>>Is the foam/LPDE combintation perfered over (as DD hinted at) something like COW?>>>

I believe so. I got the information on this Forum as to how to handle the floral foam: It comes in green blocks and is the stuff that you can easily push your finger in. I set up a table saw, or a band saw with a guide and just cut off 1/4" slices and store them in a small cardboard box. They are fragile so take care. When it comes time to load, I just push the foam over a charged case mouth and it cuts it to a perfect fit. I then seat it with a wad seater ( .100" off the powder) and, last, I place a .060" LDPE wad at the case mouth. 

There are those that claim that the plastic wads leave a fouling in the barrel. I haven't had that happen. If you wish, you can substitute a .060" vegetable fiber wad. I like the expansion properties of the LDPE wad, however, and since my wads are cut with a die, they present perfect corners to the expanding gas. In effect, they become the bullet base until the wad clears the muzzle. I believe that the wad helps keep the incidence of fliers from happening.
As always, YMMV

At one time I was using wads cut from gasket cork in my .32-40 cases and breech seating.  I would cut them to be slightly compressed from the edge when in position, so they were able to be pushed through the neck and in place over the powder (.10" or so off the powder, of course) and somewhat concave.  This seemed to work out OK, but it was slow and more trouble than it was worth, so I began to shoot .32-40 with no wad at all.  The usual disclaimers apply, YMMV!

I just hate to be the bottom post on the previous paste, so I will repost my questions here.

Is this slumping information and seating the wad .100 off the powder in Dell's book? I don't recall seeing  it. 
 
I'm doing the same as you guys expect a little different. I am loading the 577/450 with smokeless powder for Nitro for Black loads at 40% load density. I am using filler for the same reason as you fellows...kapok to be specific...to get reliable ignition with minimal concerns of ringing.   
 
I did discover that as I increased the amount of filler ES, SD and  group size got smaller.   I started with 2 grains of Kapok and gone up to 7 grains which is all I can compress in the case over the powder. 
 
I was wondering if Mr. Dell might have written on an experiments he conducted using fillers to just totally eliminate the airspace all together. 
 
I do know he mentioned that Schuetzen and Bench shooters are trying to achieve the best groups they can and filling the case with filler night not be conducive to that end.  For hunting the groups I get are just fine.

I'd like to use this quote in the book, and need your name for proper attriution.
Thanks for the data.

First post on a forum so I beg your indulgence. I have recently seen two chamber rings. One is in a rifle I own that the esteemed member hst now has in his shop that he mentioned earlier under this topic. The second is in a friend's 7m/m rolling block. His ring is precisely where the base of the bullet is when loaded with normal fixed ammo. I know his rifle was shot with cast bullet loads several hundred times in the couple of years prior to his purchasing it. I do not know if over powder wads were used. I find it interesting that these are both older rifles with original barrels.

Joe,
Do you really want more stories that show proof of chamber ringing, or do you want lines to quote that endorse your theory?
Seems the one thing that you quickly latched onto and accepted, was what you thought backed up your theory?

Yes, particularly with Dacron, but I'll take anything. The few I have to date are all in the book.
