7x61 S&H with a 2.5x8 Bushnell Scopechief IV. Wonderful hunting rifle. One of the early 7mm mag cartridges from the 50's that got beat out by Rem 7 mag due to supply and demand. It is just as effective as any other. Custom rifle made by Jay Moore of McAllen,TX. I use it for hunting. It was made my my grandfather for his best friend sometime in the early 70's. This rifle has been on expeditions throughout Texas, British Columbia, and Africa. It's partial to sheep.
