That is FMJ ammo, and not suitable for hunting. This would be a better option:
As to matching the original peeps, I wouldn't worry about it. I would set the zero to 200 yards by swapping out the front sights to the proper height with whatever ammo you choose and go from there. With a 200 Yard zero it will be +/- 3" out to 300 yards with a 150gr bullet.
