To be fair..Bigger magnification rarely gets you out further.
if anything, the bigger magnification is way more usefull close up for smaller targets and groups.

I much preferred my 10x40 fixed Mark 4 out to 1000 yds with 308, much easier to figure out your dope and hold over them fancy variable bigger magnification scopes.
Better light in odd conditions, better eye box, less paralax to worry bout Just zero it at 400 and know your ballistics.
Past 400 your wind reading ability is way more important then magnification.

spend money on ammo and shoot a lot of varying conditions for your log book instead of big expensive chit and bender scopes and what not.
