I use to use Winchester Silvertips but have since quit using them. They blow up when they hit a deer and don't always exit. I lost a decent buck due to lack of exit wound and blood trail.

I have since switched to Federal Premium Nosler Partitions and nearly every deer drops in their tracks now. The few that have run don't go out of sight.

Like you, I shoot just enough to keep the gun on target so a box of ammo lasts me for several seasons. Makes it easier to absorb the cost of the premium ammo.
