If you gentlemen have not done so it would behoove you to search out a copy of the huge tome "The Winchester Lever Legacy" by Snooky Williamson, a soybean farmer from Mississippi, AIR.
He collected and shot every model of Winchester lever guns in every caliber available, hand loading the rounds and testing them for accuracy, having fired in excess of 750,000 rounds over the course of the research for this excellent book. Load data and targets are included in the book.
I read through it last year and am still amazed at the amount of data contained in it.
Williamson was very "high" in his opinion of the '86.
