I think I have taken care of my problem with this set up which is as close to period correct and an abomination (didn't mean to get political):
The scope actually comes in two variations, 3x or 6x. I have the 3x and this helps me a lot. But I must say that the woods here in Virginia are fairly thick and a 75 yd shot is about the longest on average. But when it comes to my game shot, I want a clean kill as much as possible.
