Another good one that no one thinks about is the
Vortex Viper PST 1-4x24 . I had this scope on my 458 lott and it held up. The glass is just as clear as a VX-3 and it is tough. It has 4" of eye relief and this particular reticle is amazingly fast to point and shoot.
Reticle For a 375,you would be good with anything from 4-10 power, depending on the game and landscape.
The only thing is it is a little heavy, but that didn't seem to bother me and they have THE best warranty. Yes, even better than Leupold warranty.
