Sounds like a great hunt! Good luck. I hope to see the story & pictures posted after your success

Have yiu tried shooting with a peep sight? They make longer range shooting easier than just plain irons. I use a Williams Receiver peep sight on my Knight Wolverine 50cal. It works very well & getting a bead on game at 130-150 yards is posible for me.......where as with straight open sights I am limited to just over 100 yards before the sight itself blocks out most of the target. I love peep sights for this reason.
