The assumption is he answered your question about the ones you posted a pic of. Those are damn heavy and solid. I run them on my lightweight 338wm. If I were you, I'd check out the one piece Leupold back country. They are like talley lighteweights, but slightly different and made by Leupold. It seems like you are wanting Leupold. Do they need to be QRW/PRW though?? Leupold also makes a lighter ring than the PRW, it is also called the back country. They are made of 7075 aircraft aluminum and are quite a bit lighter than the steel PRW's. They also make a ring that resembles the Burris Zee ring that are very nice. Those are the LRW rings and are made of steel. They cost more than Burris zee's, but are pretty much the same thing. All of those would work nicely on your rifle, but material they are made from, cost and weight are up to you to decide on..
