Federal tss pattern

I think that pattern was in my dream the other night.

Mine too.  And the shells cost $5 for 10 of them. Dream big or wake up!

OP in my opinion and very limited knowledge of TSS, I think with that heavy load and .665 choke it may be blowing the pattern some.  You might try opening it up some as others have said, rather than trying a tighter choke.
