Is your feeder on private property? Are you the only person hunting the deer on this property? Are there deer there with good genetics? These are questions that I would consider before supplementing with a higher end feed like record rack. I have used record rack for several years, mixing with corn is a great way to introduce it and then the goal should be to convert totally to record rack. (In my opinion, and during antler growing season) I would only use record rack if you have a monitored herd and a controlled property, ya know, so you know the deer that are using it and so that you are not growing big deer for every one in the county to hunt because It is expensive.

you want to know the deer tho to monitor the benefits too
