So far I have only shot the Hades (15.89), Jumbo heavy diabolo (18.13) and Jumbo exact monsters (25.4). Rifle seems to like the Hades and Diabolos. Going out this afternoon to try some slugs H&N .217 and .218 dia. Slug weights are 21g, 23g, 25g, 27g and 30g. Still just shooting at factory settings. Just bought the FX Digital Chronograph to see what I'm getting for velocities.
