Just back from a fantastic afternoon of shooting Rock Chucks (Yellow Bellied Marmot) and Grey Diggers (California Ground Squirrels). Load .220 Swift = Remington cases, Fed 210, 37 gr. Norma 203-B, and a 50 gr. Hornady SP SX. That load shoots sub 1/3" at 100. Rifle was a Remington 700 VSSF. The weather was very windy and chilly, still the Swift came through... like always. Good shooting to all.
