here in pa in early season with heavy brush, i use IC choke in my 12 ga.later when leaves come off and longer shots i go to IM .
if your gun does not use them, use CYL/MOD in place of those 2.
older guns usually came in those 2 chokes.
my beretta has 5 chokes from cyl/full/
i always use low brass 7 and 1/2 in early season and no.6 in winter when shots are 30 yds out or more
people like me that dont practice shooting need a wider pattern 12 ga.people who practice can use a tighter pattern and a smaller caliber shotgun like 20/28 ga .
so, using IC in 12 ga will get you more grouse.
