From what I hear they work fine. As with any product you have the high end and low end and sometimes it does not matter. I would not spend a fortune on flip ups. A tight fit on your scope is what matters and good clearance with your gun. Congrats on your new gun I'm an 30.06 fan myself and have the one I bought when I was 18 and she still purrs like a kitten dead on accurate. With plenty of rounds to chose from.
Most shoot 150 grn well but I like 165 grn boat tails. They just shoot flatter.
