H110/W296 needs a heavy crimp and magnum primers for consistent ignition. Especially in cold weather. This month's issue of Handloader magazine has a good article on primer usage with H110/W296 and other magnum powders. My experience with it and 240 gr XTPs in my .44 mags is that best accuracy comes before max velocity. This is in my 629s, my lever carbines and the 77/44 bolt carbine. I'd rather have the best accuracy and give up 50-80 FPS. The .44 mag is enough gun for deer and hogs even when loaded moderately. For hogs, many prefer the 300 gr XTPs over the 240s in .44 because of better penetration thru the tough shoulder plate.
