Welcome to OG!!! Many guys run the IC in their guns and they pattern Extremely well. You didn't say what model gun or what shell you are going to shoot but there is Patterning Board posts for each Manufacturer on this site. Many of the guys on this site have done plenty of patterning for you and are willing to pass their information on. Go to your gun manufacturer Patterning Board section and you should see plenty of PICS and info. This is a GREAT site, even better members sharing info and run by a TOP NOTCH Admin staff. Welcome again!
