Tired of burning through scopes: need suggestion for 308 scope under $300-350

...I'm using Fusion 150 grain ammo and grabbed a box of Winchester 7.62, 140 grain to see if that round works better. Need to also order some match grade. Plan on researching here to see what people are having the best results with before ordering. I'm shooting in groups of 3 and letting the barrel cool for at least ten minutes between groupings...

This, good Sir, is your problem!!! I am sorry, but that is crap ammo and the Winchester is high priced Milsurp IMHO! Try "Remington 168gr Premiere Match 168gr SMKBTHP" or "Federal Gold Medal Match 168gr SMKBTHP". The ten minutes of cooling in between groups is good, but also give some time in between shots to cool too. The thinner your barrel, the more cooling time. Good luck
