Home Forums Hunting & Shooting Long Range Hunting Max range for a 10X scope?

I recently assembled a DIY pre-fit 308, my second very similar 308, so I decided to make this one a bit different by going with a scope unlike anything I've used in the past (all scopes are some form of Duplex, SFP), the new scope is a Leupold Mark 4HD 2.5-10x42, FFP, PR1-MOA, non-illuminated (the FFP & MOA are new to me). I've only had the scope/rifle to the range once and it was just to dial it in and check rifle for accuracy, did not check tracking by any means. Much to my surprise, the rifle liked the Hornady Spire Point 165s the best at .291" three-shot, the match ammo was .437".

To my question, I like this scope but have not used it for hunting, some same non-illuminated, FFP not so great for hunting, can't say myself but I'm most interested in what would be considered max range for a 10x scope, speaking target here, not live game (that to come later with practice, dialing for MOA and MOA trajectory confirmation).

I've heard all sorts of ideas/formulas, such at 1x per 100 yards, etc...
