My rifle is a 110, also in 7mm Rem Mag... still factory stock. It likes Federal Premium (nosler partitions) in 160gr, but also shoots the 150gr Winchester super-X realy well too, so there you go, a premium hunting ammo and a cheap practice ammo. Didn't really try anything else.

I just started reloading for it and still working on a pet load, but 60-61gr of IMR4831 and 150gr Corelokts have definite hunting accuracy (the IMR4831 60gr with 150gr CL's group very close to the Federal Premium NP's 160gr) and all of them at 1MOA or less
