|- Bullet Drop Compensation (BDC) for 17HMR & 22 Rimfire
The Sweet 17 and Sweet 22 scopes have been designed using a system developed for use by military snipers, Bullet Drop Compensation, or BDC; here’s how it works.
1. Zero the scope to your chosen distance, or instance 100 yards.
2. Loosen the locking screws on the elevation drum.
3. Turn the drum until the 100 yard marking matches the elevation turret indicator.
4. Re-tighten the locking screws.
You can now compensate the trajectory of a bullet at any distance simply by using the parallax adjustable objective to measure the range to your target, and setting the elevation turret to the required distance. So point of aim and point of impact are always the same; it really is that simple!
The Sweet 17 is specifically calibrated for the 17 grain HMR bullet, and marked for ranges from 100 to 300 yards, while the Sweet 22 is calibrated from 50 to 175 yards. The Sweet 22 is also supplied with three quick change turret drums, each designed for use with the most popular weight bullets, 36, 38 and 40 grains. All Sweet scopes feature fully multi-coated precision lenses, a parallax adjustable objective lens, and are waterproof, fog proof and shock proof.
