What is everyone's thoughts on shooting during the hot summer months? What all does the extreme heat really effect besides keeping the barrel warm. I am wondering how much the heat can play in the accuracy of firearms I was out shooting the other day and my guns I took using their hand loads usually produce really nice groups instead no matter how I shot they would not group together. I was wondering if anyone has any tips and tricks for shooting during warm weather. I've seen match shooters shoot incredible groups in the hottest of weather and I was wondering what they might be doing that I could try. I have talked to a few people I know about this question and they were saying it was probably shooter fatigue due to the heat. Is this what you guys experience or does the heat actually do something more to my guns that I can better protect against so I can keep practicing all summer in preparation for the fall hunts! Thanks guys hope my post isn't to confusing or vague.
