Browning Gold 3.5 NWTF Edition, 24" b..... Would you guys guess a .670 constriction would be about right for shooting Winchester HV 3.5" 2oz 5s and the Double XX 2 1/4oz 5s??? I am really wanting to shoot 5s, so my question is, is .670 about right for the 5s or do you think i Need to shoot something closer to .665???
