The .220 Swift cartridge presents a dilemma for shooters. Short, light bullets offer maximum velocity—possibly at the expense of barrel life—and flatter trajectory. Heavier, more aerodynamic projectiles at slower speeds are gentler on barrels and more resistant to wind deflection. Having used bullets from 40 to 70 grs. in a variety of rifles, I suggest the flat-base, 55-gr. Speer TNT hollow point for rodents and small predators at longer distances. Propelled to 3828 f.p.s., the superbly accurate and fragile projectile drops only 6.7" at 350 yds. and 19.8" at 450 yds. with a 250-yd. zero.
