Shot the Federal Heavyweight Flite Control 3.5" #6's today from a SBE 2 with an unported XX full aftermarket turkey choke but the maker is unknown. Nice uniform pattern with out any holes in it. It put 83 pellets in 10" circle at 40yds. Plenty good enough to kill a turkey at that distance. With the federal heavy shot it is equivalent to #3's in lead. Lots of energy left at that distance.

However, this is in comparison to the Nitro 3.5" 4,5,7 combo Hevi shot from a Rhino Choke .660. The 10" circle contained 279 pellets but there was a golf ball sized hole in the right center. Too much difference for me to ignore.

The Hevi 13 "mag Blend" 5,6,7 combo put 201 pellets in the circle with another SBE 2 and a Jelly Head choke. Pretty good backup load and much cheaper combo.

I shot quite a few other combo's if anybody has a question then please let me know. I shot 2 SBE 2's, an Extrema 2 and a Franchi.
