On second thought it might be a bit heavy. Even though it has a sling it has a
two piece stock? It is most likely a straight barrel. The Pedersoli Jagger has a
straight barrel and is pretty heavy. The .54 is right with 1:65 twist. I would
try to keep the weight down by using a swamped barrel. It would balance better
too. There may be a happy medium with recoil reducing stock design and lightest
weight possible. I wouldn't want to hold a heavy-ish rifle all day. On the other
hand I wouldn't want to shoot an overly light rifle all day either. Food for
thought.
