Yesterday my buddy and I went deer hunt and I spotted a deer up on a rocky bluff at 658 yards he was about 500 ft higher than we were so we hiked up to the same elivation he was at and ranged home still at 658 I was shooting a Remington model 700 7STW with 162 grn hornaday SST ammo I shot at the deer 5 time hitting it 3 out of the 5! Two shots were in the from shoulder and one in the back of the head it seemed that if the bullet ricoshaed off the back of his head. The buck ran around for long enought for my buddy to get a shot with his 7mm using 140 grn nosler partitions and he hot the buck 1 time in the chest dropping the buck where he stood. Not really sure why my gun didn't bring the deer down considering I shot a bear a week before that @ 350 yards with the same gun and ammo and the bear dropped where he stood!??? Can anyone help me on trying to figure out why the deer wouldn't go down? Thank you.
