I'm pretty impressed with this setup

Looks good. Pretty similar to the results I got with my Weatherby, same choke and shell combo.
Good looking pattern.

What is the Sumtoy you are using?
Wow that's impressive. The sumtoy-heavyweight combo is killer!
I believe its a .562 but I cant say for sure, because I dont have it with me.
