Why would you say that? You don't need a magnum rifle for deer.
I have one and can vouch for its accuracy when I shoot the Remington accutips.
"The new Savage 20-gauge Model 220 F is a true bolt-action "slug rifle" that
delivers minute-of-angle accuracy at 100 yards, effective range to 200 yards, and more power than either the .454 Casull handgun cartridge or the .45-70 Gov't. in a rifle. It is not just state-of-the-art, it advances the art. It gives slug gun hunters the firearm they have dreamed of for many years, and for most hunting situations in the eastern half of the nation, it makes a centerfire rifle unnecessary."
