I run a couple of vx6's, and they are solid scopes. If your on a budget, go with the vx3i. I have one on my 7mm-08 with CDS but haven't contacted them to get my custom dial on any of them YET. It does the job for that little rifle. For a 300 wsm, I would get the vx6 if you can afford it. It is a great scope but make sure you have great rings with it. Another option is the vx-R. They have similar glass to the vx3i and some say it's not as good, but I can't tell much of a difference. Illumination comes in handy in the moment you need it.
