HPR 1800-2000, LPR 170-200, DW 20-27. 820-855fps the few times the chrony actually read different tunes. Can't get the chrono to read enough shots to get any kind of string to establish an ES. Cleaned the barrel before i started slug tuning, haven't found a tune that groups under 2" at 100 yards. I can shoot those kind of groups all day with 22g pellets. Yet I was able to shoot a 5 shot 2.5" group at 170 yards the other day with the sniper slugs, been shooting with no wind. Got 400+ alatros kings on the way and looking at a new chronograph as well.
