Federal Heavyweight 7's Pattern Pitiful

[K9Doc]

Thats the highest 40 yard 10" count i have ever heard of anyone getting. There are not many pellets in that load, I think only around 415 in the 12 gauge 1 7/8 oz.
What gun, choke, ect....?
Thanks

870 super mag,, 1 7/8oz 3.5" 7's. I shoot them through a briley hs turkey choke. I think its a .675.

I get 190 with a browning citori and a .665 ext non ported choke. My other gun gives 216 with a mossberg 935 and a .675 carlson ext non ported choke.

All of these are in 10" circles at a measured 40 yards with 3.5 " federal HW #7. Both guns have 28" barrels also.

thanks
