I have a 8x32x56 s111 sightron rifle scope with an lrd reticle. I was wondering if anyone can put custom reticles in this scope. I might use this for f-class shooting and am wondering about my options. I believe the current dot reticle is too big for shooting small groups past 200 yards. I have only used it to 300 yards and the dot was too big for that. Thanks.
