These loads are Old School, I have been using them in the 44 Mag since 1970.

With typical "store bought" hard cast 240gr SWC bullets, in 44 Mag brass, start with 7.5gr of Unique.
Then load some with 8, 8.5, 9, and 9.5 grains of Unique. Pick the load that has the recoil/accuracy you need.

I like 7.5gr of Unique for double action range use and practice.

The wife and I use 9.2gr of Unique for our general purpose and deer lease field loads, [I load on a progressive loader and I have a powder slide that just happens to throw 9.2gr of Unique.

If I want something hotter than 9.2gr of Unique I go to 2400.

For heavy loads in a 6+inch 44 Mag and especially with bullets over 250 grains I use H 110.
