Today i went and patterned the two guns i plan on using this year.  The first was a browning maxus with a heavy 13 (664) choke.  The second was Moss. 835 with a truglo (695) choke.  
Maxus:
40 yards 2.25 mag blend- 225
40 yards 2oz Win supreme (3.5in) #5-91
835:
40 yards 2.25 mag blend- 210
After shooting the 835 the first time my shoulder could not take anymore.  I have a pure gold for the 835 on the way and also hevi 13 #7.  Any thoughts or suggestions?
