I have been shooting and reloading for the 44 for over 20 years now and I too shoot a SRH 7 1/2". Had mine Mag-na-ported when I first bought it. An old fellow who had been loading the 44 for many years when I started told me that his secret for accuracy in the 44 was to push it hard. Ever since then, I have been doing just that. Most of my hunting rounds are near max load. I've found that they are more accurate than the softer loads but I have to tell you, the 300 grainers on full power will let you know you're shooting something. For deer or larger, I don't recommend anything lighter than the 240's. Good Luck.
