You'll come to love the 375. I have two a Pre64 M70 and a Ruger #1. I have managed to work up a light load using a 225gr flat nose pistol bullet (I think thats the bullet weight but memory is a fickle thing and I'm to dam lazy to go downstairs and look). It feels like your shooting a 243 and will flatten a deer. congrats again on your new rifle, it will become a favorite.
