Great article, but I might suggest there is a 4th reason air rifle silhouette is a bit easier...the bullets are not scaled down (well slightly I guess, 6mm to 5.56mm). Shooting a ram at 45 yards with .22 air rifle pellet is roughly the equivalent of shooting a full-bore ram at 500m with a 2.2inch (or 55mm) projectile. Can't tell you how many times a 55mm projectile at the rams would have helped my score a bit.
