For fixed ammo, I've used that charge of 4759 behind bullets from the old stand-by 165 grain (a version of which is still available from Lyman as the 319247 if my froggie brain recalls correctly) to the long-discontinued Ideal 31952 in 200 grain weight.  It just seems like a good place to start with any reasonable bullet weight.  I also used it a bunch with my Green Mtn barreled high wall takedown to breech seat behind the 319289 and the recently re-released WH French bullets (both at about 185 grains) among others.  It may not be the ultimate charge for all of them, but it seems like a great place to start.  No guarantees, though.  YMMV.

"Your Mileage May Vary" or your results may be different from mine.

Do you have the Ideal 31952 mold in 200gr?  Because it is a variable single weight or the Perfection mold 75 - 225gr

31952. This series of bullets is known as the .32-40 short point. They have become very popular. For different purposes all of the weights have friends. No. 3 special tool only made to load them.
(PB, FN, 75, 100, 125, 150, 175, 200, 225 Also perfection - TP is 295)

Yes, mine is the single weight version, 200 gr nominal weight, so one groove shorter than the very longest.  It IS the old fashioned integral type, not separate blocks and handles.  I have done some really good shooting with this bullet and can see why the Perfection mould in this design would be a great one to own.

About 20 years ago during the early popularity of  BPCR competition, Browning built 40-65 rifles for competition for about 3 years. This was about 1996 to 1998 or 1999.  These rifles were built on the 1885 Browning HighWall and it is important to keep this in mind about my loading data.  My data may be over pressure for a cast iron rifle like the Ballard that blew up at a match. 

Lyman marketed cast lead  LRHP 400 gr Snover bullets for .40 caliber BPCR rifles in the early 2000s.  They included a small chart of pressure tested loading data for the .40-65 Win for use only in single shot rifles.

This chart included data for SR4759. The Lyman data for the 400 grn bullet started at 17 grains (1140 FPS  and 8,900 PSI). 
It maxed out at  21 grains  (1373 FPS and 17,900 PSI).
If you search this site you can find the table from the Lyman data. I posted it here 4 to 6 years ago.

From that data I interpolated data for another bullet weighing 312 grains.  I used the same Lyman data with the lighter bullets and had zombies (unburned powder grains) left in my bore. I do not like like running over powder grains with the next bullet or having to blow them out so I boosted the powder charge to 23 grains of SR4759. The bigger charge burned cleaner and the zombies disappeared. Groups shot using the tang sight are near 1" at 100 yards. 

This bullet is the NEI gas check #206 bullet made for the .405 Win. This bullet was under size (for the .405) at .410 diameter and it worked perfectly in my rifle's .408 groove diameter.
