depends how far you are shooting and how good yer eyes be I guess.
mine are no longer what they once were.
I am good with open sights out to around 100-150 or so. with 100 probably being more realistic.
all my rifles with scopes ,I put the 3X9X40 vx-3 Leupold on them.
I seldom shoot past 400 yards and will only do so under perfect conditions with regards to wind , rifle rest and such.
imo, this scope is more then satisfactory for 90 % of hunters.
if your goal is to be one o them long range sniper hunters ,I would recommend, in the words of tim taylor "MORE POWER!!!!!!!!!!!! "
I have two family members who are snipers in our military and while I have no desire to take such shots myself while hunting , I am in awe of their abilities to do so.
just be sure to put in a lot of range time before you do so ,if you decide that is you desire.
my best advice is to know the capabilities/ limitations of yourself and your tools and use wisdom in your choices.
