Cooper 21 20TAC Stabilizing 40grn?

Anyone shooting a 20 cal Cooper out there that can advise me on stabilizing heavier bullets? I assume my rifle is 1:12. I know some rifles with 1:12 will stabilize a 39BK and 40vmx but what are you Cooper owners seeing?
Just thought I'd ask before I start sending test components thru paper.
Thanks
