Sir Ron,
I think your about ready to go "Creedmoor" with that rig. On the Square versus Rectangle; wise choice. A Square table allows room for each knight in the growing membership to line up their 458WM's in front of their place irrespective of the number they bring. My one Whitworth has room to breath sitting across from your Wolf pack and all their friends on our growing square table. If the table was a rectangle we might have a problem with space!
My Favorites are the Ruger Canoe Paddle Stock and the #1 but if I got a call to Judea & Samaria, I might like to borrow Freki and a bucket full of the 400 twins. Should be sufficient as a stopping rifle all the way up to Toyota's.
