My magnum is a .391 Rumpripper Magnum. I have a 40 power scope on it with a laser range finder and a bullet tracking GPS.
My bullets are packed in salt.
They need to be so that my game doesn't rot because I shoot game so far away that it'd be ruined by the time I can walk the 5 ridge lines over to it. The salt preserves the critter.
The GPS bullet tracker is an important component to my shooting as well because often the game I drop is so far away that it'll be covered in snow and or the mountain will have changed elevation before I can walk over to it.
