I too have a M696 and I second the opinion of shotguntom. The M696 forcing cone is too thin to trust to anything leaning towards "hot" or "jacketed" for that matter in a .44 Special.
Anybody who is "pushing" the M696 and doing okay is just lucky that the forcing cone hasn't failed.
S&W K-frame revolvers, and I have heard even in .38 Special, but especially in .357 have split their forcing cones. So have Colt "D" frames in .38 Special as in the Detective and the Police Positives.
I will be shooting my M696 with soft cast lead 240 grain bullets at about 800 to 850 fps. Still a very potent load. It would be potent even at 750 fps. A lot of people and critters have been done in with the standard .45 Long Colt load of a 250 lead bullet at about 800 to 850 fps. Even grizzlies.
I even think jacketed bullets in the M696 might be unwise. Also, it is suggested to keep the forcing cones clean in the above mentioned smaller handguns, might be a good idea with the M696 as well.
