Sorry for your loss. I own 2 Stainless Vanguards, a 270 Win and 7MM Mag both will shoot groups under a inch at a 100 yards. No problems with either, for last 4 years.
Hope you reload, shells are pricey. I like RL26 and Norma MRP powder. 115gr Nosler Partitions, bullets work best in my Winchester 257 Roberts.
