Load your SWC over 8 to 10 grains of Unique in magnum cases, no need for magnum primers. This is the only 44 magnum load I use for everything. I shot a 245gr Keith bullet over 9gr of Unique through a 6’ blackbear on a diagonal from shoulder to groin. Only reason I switched to 10gr was because accuracy was a little better.
Hard to beat!
My go too load is a 250 gr WFN LBT hard cast bullet over 10 grains of Unique. It slays big ole feral hogs here at the Ranch like Thor’s hammer.
