My farthest shot was 535 yards with a 22-250 ackley improved. Leupold 6.5 to 20 pushed up to 8.5 to 26 and dots set for different ranges by premier reticle. Also have hit a few prairie dogs at over 1000 yds, but haven't been able to keep them from going down the hole. It starts out at 3800 fps with 55 grain ballistic tip. Is just going 1100 fps and drops 21 feet at 1000 yards.
