No. Zero with your carry load SS198. When you practice with 40gr AE you have to adjust the rear sight "up" about 10 to 14 clicks. The rear sight is clearly marked "UP" which is the counter-clockwise direction.So would u turn clockwise or counter to zero for the ss198 ?
When you are done with your practice load and are going to carry adjust the rear sight "down" (clockwise) 10 to 14 clicks.
Repeat each time.
