I load mine with a Lee 255 grain RNFP at 1525 f/s. A dead-on zero at 50 yards is 6 or so inches low at 100 for me. Set up with a Marble tang sight. Don't know if it's the rifle, my eyes, the load or sunspots during the Vernal Equinox, but a 5 shot, 5" group at 100 yards is the best I've ever done. At 50, I can get 5 shots in one hole. It's deadly though. Furthest shot I've ever taken was on a 250 barr hog and had complete pass through at a paced 90 yards. Don't think I'd go much beyond 100, not because it won't do the job, I just can't do my part.
