I have a bushnell 4-12 on my 300 win. that I bought for 70 bucks at Wal-Mart. I have about 150 rounds through the rifle, 3 years of hunting, and it has yet to fail me. I keep thinking about getting a more expensive scope, but this one has given me no problems, so I cant justify it to the one in charge of the money (my wife). I read somewhere that if a scope is going to fail, it will be in the first 50 rounds fired, so I guess i am safe. maybe i just got lucky, but i have to say I am pretty Damn happy with it!!!
