I would suggest you rebuild your arrows using feathers instead of vanes, it will help bring your foc up as feathers weigh less than vanes. You are shooting a relatively light weight point, and need to lose some weight on the back end if you are having a problem, which is what I did. If losing grains in the rear gives you a grains per pound issue, simply increase your head weight by the weight difference between the feathers and vanes, which will correct it plus further increase your FOC. I would try the ACCs with vanes and your 85 grain head, if they fly and group good, no problem. If they don't, swap out the vanes for feathers. If that still doesn't solve the issue, you'll need to bump up your head weight.
