If you have antimony in your alloy, hollow points are varmint bullets only. The HP portion of the nose just frgments instantly as it opens a breaks away from the body. If you use it on big game, use tin lead alloys only, and live with the speed and accuracy you can get.
However, I strongly advise that you NOT use HP's on big game. You'll get far more reliable and quick kills with a non expanding bullet wearing a large meplat, much larger than your Keith, though it will do a good job if driven at full throttle. The LBT WFN and WLN designs have a meplat diameter which is .090 smaller than bullet diameter, which is .340 wide in your 44. Rarely will a deer move from where it is hit with this bullet if start velocity is 1200 fps minimum and not over 1500 fps maximum.
They never stop in game up to elk with quartering shots and rarely in large bear and moose, but they kill efficiently. We cannot measure killing efficiency by energy transfer. Game doesn't comprehend our false training and will just run off if we use that concept with large bore handguns. Read on down through this forum and you'll see many references to my Displacement Velocity (DV) formula for calculating killing effectiveness.
