I'll speak up. I've had low power variable Leupolds on 458s, 416 Rigby and 375s. All of them held up better (and still area). in turn, the easiest scope I found to break was a low power Burris. Ten shots from a 338's all it took. My current 416 Rigby has a Leupold 1.5X5X20 on it and I've fired at least 500 rounds with no problems. The 375 has a 1.75X6 and that one has close to one thousand. I got rid of the 458 long ago, but that 1X4 was one there for at least a couple of hundred rounds with no problems. I've owned them all and for durability, the low power Leupolds are my recommendation. jorge
