"Sweet Series Scopes: This family uses trajectory compensation technology that was originally designed for the military sniper. However these hot new scopes are catching on Fast with Varmint and Target hunters. They feature a quick change turret system specially calibrated for multiple grain weights for the calibers: .17HMR, .22LR, .223, .243, .270, .30-06. The main features of the Sweet 22 are their ability to compensate for bullet trajectory by specific grain weight. The elevation drum will compensate for .22 cal grain weights of 36, 38, and 40. The Windage and Elevation turrets have zero reset with ""Allen"" screw. Each model in the Sweet 22 Series have an adjustable side parallax setting of 7.5 to infinity. (With the exception of the model S22-618x40SP which is 10 to infinity) The elevation turret has on outer fixed wall with two window cutouts. Compensation markings for the bullet weight are shown through these cutouts. The elevation turret has an inner drum that turns when adjusted. The outer portion of the turret is fixed with the window cutouts which will always face the shooter directly when the scope is mounted.|The Sweet 22 is 1/4 MOA, that means one click will move the bullet 1/4"" at 100 yards. If you zero at a different yardage, say 50 yards, one click will move the bullet only 1/8"" at 50 yards.|Calibrated for the .22 LR|Side Parallax Adjustment|COMPENSATION DRUM: .36gr., .38gr., and .40gr.|Limited Lifetime Warranty.|Export of this product outside of the United States of America is not allowed and is controlled by the US Department of State"
