Absolutely this is a good cartridge for the 44 SP. Especially if she can shoot it well. I do know for a fact that the 240 and 250gr both running about 900FPS out of my 4 5/8 Flattop will do the job. This has a large meplat and will punch a big enough hole. The accuracy should be there to 50yds. I believe she will bring home venison.
