Handed

I've noticed on a few episodes that Lucas writes with his LEFT hand but on the episode "Sporting Chance" where he shoots against the dapper gentleman from England, when shooting at a target, he shoots with his LEFT hand and when he shoots at cans thrown in the air, he fires his rifle with his RIGHT hand and when shooting at bottles on a log, he fires with his LEFT hand, but when he shot the bad guy at the end, he fired with his RIGHT hand again.
