[QUOTE="tug, post: 5701836, member: 4692"] Unless you understand subsonic ballistics, this won't make much sense. If you understand the principles of subsonic ballistics, this makes perfect sense. Without getting too deep, E=m x V2. In this case, we hold V constant. That is subsonic velocity, let's say 950 fps. To increase energy, then we can only increase mass. In this case, to around 300 gr. Now to bullet design. A .44 mag can be loaded with 300 gr bullet to 950. But a 300 gr .44 mag ballistic coefficient is about .245. A 300 grain 8.6 is about .750. You can shoot a 8.6 out of a semi auto. You can shoot an 8.6 at ranges over 400 yards. There is something to be said for hitting a target at 400 yards in complete silence. [/QUOTE]
