Here in Michigan, we would need to recheck our sumer sight-in's at the end of October. Most of us won't even sight-in this time of year.Our mid-summer outdoortempsand November hunting season temps average around 60 degrees difference.So generally, if I'm at the range this time of year, I'm usually there with my open sight riflesjust trying different products for likeness & consistency... leaving my screwdrivers at home until at least mid-September.

I will only bring such tools to a range in July if I just purchased a new rifle & want to get it somewhat close on paper until the fall season arrives.
