Did a search on the page, and the word "shotgun" is written only once, and it's there describing the guns the fish and wildlife guys were carrying. The Remington 700 is a bolt-action rifle, and in case, was chambered in 6.5mm-.06 caliber. The Remington pump shotgun you're thinking of is the 870.
Remington makes a pump rifle. The 760/7600.
