I am buying a 300.wsm and i would like to set up a nice scope on it. I am currently shooting a 7mm rem mag and it does almost everything i need but my scope is ------. I want the 300. wsm for the big game and long shots. I was looking at a Leupold 4.5x-14x, 40mm with CDS in VX-3. Im not fully sure how it works though and was wondering if anyone knew. If there is another scope out there that is also really good and is under 800 dollars please just let me know. Im not sure how the turrets actually work and i would like to know how the CDS and other turrets work?
