I remember when I started hunting turkeys that I did not know anyone who "patterned" their shotguns. Most just went out and tried to shoot a turkey. Fortunately, we've learned over the years to see how our guns/chokes/shotshells work at various distances. That's a very good thing for us and for the sport.
It's very heartening to read that folks here know what works for them. That, in the final analysis, is what's most important.
