I have a leg in each camp here.

Firstly, I wouldn't dream of using fillers in full nitro loads, but then I don't use RE-powders ever. ADI (..or Hodgdon 'Extreme' powders) are bulky enough not to require wads or dacron. There is usually a small air-space, but load densities are probably in the order of 95%. No cause for concern there!

(Note exception: .450 #2 and .475 #2 probably benefit from filler, even with ADI/Hodgdon 'Extreme' powders)

Secondly, most 'nitro-for-black' loads DO need filler or wads, and I strongly prefer saddle-felt over foam or dacron/kapok, as others here must know by now. I have concerns over the longevity of polyurethane foam in the monsoon tropics where I live, as it breaks down to a crumbly or gooey mess in a couple of years when used as packing, or in boot-soles, luggage padding, etc. Wool felt, on the other hand, has been retrieved intact from pharoahs' tombs!

I have also found foam to be 'grippy' on the internal case walls, such that it can be compressed within the loaded cartridge by the powder charge if transported bullet-down, and then remain so, causing air-space between the powder-column and the compressed wad.

This is just my long-winded way of agreeing whole-heartedly with the posts of Bill and others:

Ken,
I do agree with you.

“ I still thinkif a manufacturer does not recommend something there is a reason.”

That reason in this case is “product liability” When a manufacturer ships loaded ammo he I pretty sure it won’t be altered before it is used and will function as he intended. With the use of components the manufacturer can’t be sure you will do it exactly as the recipe calls out. I believe in the case stated in this post and on other forums the individual did not use the foam fillers correctly. Better to error on the side of caution.
Bill

I cut my own foam fillers and have for the last 6 years with no problems whatsoever.
