I just had the same choke delivered last week and am hoping my results are exactly what you've got there. I'm going to alternate between the .585 Trulock and a .570 Sumtoy depending on where I'm hunting - Trulock for places where I'm expecting closer shots (thicker, steeper, etc.) and Sumtoy everywhere else for a little hotter core (~320ish in the 10" at 40 yards)
