320 yards with a 257 weatherby magnum. ain't got to many places to shoot over 400 yards.
so we got into using single shot pistols and i have killed 10 deer
between 225 and 280 yards with a BF hunter silhouette pistol in 7mm Benchrest Magnum.
EABCO.com makes them. nice little rig. and some of those were killed with T/C contender pistol in 7mm Bellm.
all of this shooting was done with sandbags or someother rest to steady up on.
here is a picture of a rest i built to shoot longrange. i have never shot at anything but targets with it.
but i did use the wide forend to hunt off sandbags with. works pretty good out of a built treestand.
