John,

Certainly groundhogs start to appear small at two hundred yards.

I have a Burris Signature Select 4X-16X 44MM Ballistic Plex reticle on my Remington 700 SPS DM in .243 (it's my predator rig), and I use Hornady 75gr. V-max.

My .204 wears a Burris Signature Select 6X-24X 44MM Mil-Dot reticle - Savage 16 FCSS Weather Warrior - Hornady 40gr. V-max
