Fireguy, I have a 6x18 Burris Fullfield on my 6.8 currently that I'm using for load development. it's an OK scope but IMO not in the same class as my Leupolds or Bushnell 4200's. I just got my 1.75x5 Burris (an older Fullfield) back from them for repair work due to a cracked lens and canted reticle. It's like new again and they stood behind their warranty. I will probably mount it for hunting once I get a good load dialed in. If I were to buy a new scope for the 6.8 it would probably be a Leupold III 2.5x8. There's a good deal on them from Midsouth Shooters Supply now. Just remember you really get what you pay for in optics so buy the best you can. BTW were are you shooting 300 yds.? South FL?
