Good choice of gun, and good choice of ammo. But, about the ammo, it really depends
a lot on what you'll be hunting, and the terrain (open vs. wooded/close in, etc.). Each rifle is different too. Some, like my .270, like the Rem.150gr. ammo, and I get good
accuracy with it. Hopefully, your rifle will "like" it too, but don't be dismayed if it doesn't.
You may need to try several different bullet weights, and brands of ammo to find the one that YOUR rifle likes best. Good luck.
