Winchester SX3 with IC .675 what shells/size to try?

[Ocoee Ridge Runner]

Hevi-13, Magblend, Winchester supremes? Looking to pattern this new gun for the first time.

Thanks

I'm shooting the same gun but with the IC.665, Hevi #7's shoot great out of it, before them I shot Winchester XRHD# 6 and got very good patterns.

Hevi 7s, then Hevi 6s.

Do you guys have any experience with the magnum blends out of this gun?

My gun shot them ok but it wasn't better than the 7's and wasn't but just a few pellts better than the #6 but I've got a buddy that gets great patterns out of his Invector plus BPS and a kicks tube.

I have the SX3 with a Pure Gold .670. I shoot the Mag Blends. I have taken birds at 50+. Great pattern. I have tried the Nitros and get about the same pattern. Good luck
