I talked to Mike at IC about swapping a choke and told him I was thinking of swapping ammo and he asked me what I was going to shoot, I told him Winchester XRHD #6 and he recomended a .655 constriction for my SX3, anyone have experience with this choke before I shoot, I just recieved it priority mail today, How do you think it would do with Nitro strait 7's? On the choke it says Ray Eye Edition 2009.
