While there are many bullets more than capable of killing a deer past 350 yards, my problem is the terrain where I hunt. Most open areas that allow a longer shot will be surrounded by thickets so bad that unless walking within ten feet of a downed deer, locating one is tough. Most bullets I've used (factory loads) will certainly kill but they will not leave a blood trail to follow since they won't pass through deer at longer ranges. The few bonded bullet loads I've tried will pass through but a 7mm R Mag seems to lack the velocity necessary for them to open up much past 400 yards, exit holes were dime size. Anyone else have this problem? If so, how did you solve it?
