Ive got a Browning Gold, same choke and barrel. Mine loved the Kicks GT .680 with Win XR 3.5" 6s. Great hunting pattern, very even pattern at 40yds. Still killing pattern at 50. I just got a Pure Gold .670 to try in it in next couple weeks. Buddy of mine shoots a .670 Jellyhead with MagBlends in his Browning and its MEAN, but very tight. He missed 2 birds last year within 15yds. Im gunna try MagBlends in mine and Win Xrs too.
