What is your O.A.L. with your 22-284 and 80's?
With Rem. 6mm brass getting so hard to find my dad's TTH (22-6mm) could be getting turned into a 22-284 sooner rather than later but his TTH is built on a Rem 700 Short Action and I'm not sure it will be long enough when loaded with the 80 or 90 grainers. Maybe with an extended mag box it work better in a SA 700.
