Thanks all. Know of all the brands mentioned and thought of getting a Winchester and converting it. Hoping for something shorter than a standard action but longer than the short action set up for .308 type cartridges. Montana Rifle Company had one that would handle 3" I believe. My current .284 is a Mod 88 Winchester and requires loads that accommodate bullets that are good at 2.800" as you know. It was mentioned how the .257 Roberts does better in a longer action too. That is the one criticism I have with my Kimber in that caliber. It will only accommodate 2.800".
What OAL can the Tikka handle?
I wrote Barrett when they were still making the FC asking for a .284 Win in it. Turns out I wasn't the only one, but we know how that turned out.
