Depends. What purpose are you planning on using gloves for? For cold weather shooting I usually just use a pair of wool, gloves with a waxed leather palm (for grip), and cut off the fingers (of the glove ) to about the mid nuckle. I use the same set up for cold weather only... when pistol shooting, waterfowl hunting or big game hunting. Never had a need to wear gloves for shooting any other time. Make sure that your golves have a gripping material on the palm and bottom fingers. Wool on it's own againts steel is pretty slippery and doesn't grip well.
I'm using gloves for two purposes: range and field. At the range, I'm trying to get comfortable with my new sidearm, a Ruger revolver in .454 Casull. For that, I got a pair of PAST gloves, which do seem to help with the recoil somewhat.
For the field, I stumbled onto some Gates all-leather gloves that have been discontinued, and so were a great deal. I haven't tried them, but I expect they'll be OK. Mostly I was looking for a recoil reducer for the hand cannon mentioned above.
Others have offered up a sighting of roughly 2 inches high at 100 yards as a good sighting scheme. In my own experience I have come to favor a sighting of 3.5 inches high at 100 yards. This allows for the individual to hold dead-on (directly in the middle of the top and bottom) the animal out to roughly 350 yards.
Magnum calibers such as the 7mm Remington and 300 Winchester will extend this slightly. At 400 yards I hold directly on the backbone of the animal. The drop at this range allows the...
