Any recommendations on a vise good for sighting in rifles?

Caldwell Lead Sled

Save yourself some time, money, and hassle. Just get a good set of sandbags and an adjustable front rest. Gun vises are a real pain because you have to reload and when you do the process of realigning the gun in the vise starts all over again.

Uncle Buds Bulls Bag. Good luck.

Criggster's right............both the leadsled and vises are a tremendous pain to realign after reloading for the next shot. The leadsled does reduce felt recoil dramatically, however. If you are recoil sensitive and shooting a big one, they are a good deal. A good set of sandbags and an adjustable front rest are hard to beat, and are the mainstay of most.
