I shoot a fair amout of 4759 in the 38/55 and never use a filler of any kind. Generaly fillers help to make a powder thats intended for a  higher preassure cartridge and load work in straght sided black powder cases.  4759 was designed for mid range loads at lower pressure and is best shot without anything else in the case.  The filler materal will change the buring rate and could well create too much preassure for that powder/case combination.  I don't have my load book at hand right now so don't want to pass along my exact charge from memory. I am sure someone will post good starting loads. 1200 fps is a good place to begin.

On wads. 

I use them in two of my 3 38/55 loads.  With Fixed Black powder loads I use a thin card wad to protect the base of the bullet.  While I buy them pre-made from Walters they are about like the materal a deck of playing cards is made from. That would be a good place to get materal for thin wads.

Breech seating Black powder I use a Walters wad over the powder to keep it in the case while loading. It needs to have some thickness in order to stay in the mouth of the case and not let powder spill into the action. They are thicker and sort of spongy, I don't know exacly what he cuts them from.

In fixed loads for smokeless I never put a wad in the case. Breech seating smokess either. With smokeless he case is about half or less full of powder and I can get it into the chamber without spilling.

As a rule don't use a wad if you don't have a good reason to.  They add another varable, less varables the better off you are

Using a wad will make "LESS PRESSURE" then without a wad!!!!!!!
Yes I said it right "LESS PRESSURE"

Another powder that you might try for breach seating is Vihta vouri N110. It is a stick powder that looks a lot like 4895. Its performance is similar to 4759 except it burns clean. No unburned powder left in your barrel. I have been using it in 38-55 and 40-70s with good results.

Boats, I agree one hundred percent.  The load's I posted were used to test a barrel that I had just lapped.  

I thought those loads appropriate for starting loads.

The rifle I'm working with is my black powder schutzen rifle.
