Has anyone patterend this load out of a rem 870? What choke constriction is reccomended?

I've shot them out of a Undertaker Hevi Shot choke... They shot ok... But my Win Ext Range out shot every thing I've ever patterned...

I agree the Win xtended range shoot the best that I've found, except for the nitro shells but I'm out of them and not spending the extra money for them when the win. pattern almost as good. They pattern just as good they just don't have the #7's punching all those holes in the paper.

I use them in an 870 super mag, 3.5 inches with an Undertakeror a Jellyhead. They work great for me. As for choke constriction .665 or .675 work best with the hevishot.
