Lyman say 9.1 to 12.6 of 231 with a 200 gr lead boolit. You'd probably have a good plinking load at 10.0 grains. The 240's are going to do better with a slower powder like 2400. You absolutely have to crimp them for a revolver. I would advise against you trying H110/296 yet because it can be touchy, and you sound like a newbie to reloading. A newbie without a manual and a 44 Mag?!
Go buy a manual, and a LB of 2400. 2400 is a very forgiving powder to load with and works very well with lead boolits. Especially in 44 Mag. A good powder for you to learn on.
