I've been shooting Savages since December 2000 and I'm with Randy on his choice of powders. 5744 ignites easily, is forgiving of minor variations in loads, seems to produce great groups with almost any bullet of .451 diameter or larger and you really have to work to get it to misfire.
Believe it or not, my load for plinking and jackrabbits is 45 grains of 5744 behind a .457 roundball in an ordinary MMP sabot. I have no idea of the velocity but I can consistently knock off beer cans at a hundred yards with that load.
I don't care for the Lee loaders. Instead I use a BP measure from Bass Pro that is calibrated in five grain increments. The Item number and description is 38-861-361-00 ADJUSTABLE POWDER MEASURE 5-120 GRAIN. They cost about ten dollars plus shipping. I believe you can find them at:

I buy Strait-Line brand chalk line chalk in plastic bottles from a local hardware store for a little over a dollar, dump the chalk out and use the bottle for a powder flask. With a little practice it becomes second nature to pour so as to produce very close to the same amount of powder each time.
I've found that the weight of the measured 5744 is about 5 grains less than the indicated volume so that a 50 grain measured load weighs about 45 grains.
If I'm seriously shooting for groups I weigh my loads. Otherwise I measure them. I think a scale would be a good investment though just so you can check the weight of measured charges from time to time.
For a starting load, I would recommend 45 to 48 grains of 5744 behind a .452 diameter 250 or 300 grain bullet (Hornady XTP's are cheap and readily available most places) in an MMP or Hornady HP sabot.
