I am not really worried. But curious. I have 100 yard range and like to hand load. Last 2 years I didn't practice like I normally do. Fine for hunting and more than most. I had notes the one was a to the left. Also comes down to where I left my hold over.OP, if your only shooting 50-60 yards in the thick woods and swamps of MI's UP, and your off only 3/4 to 1 1/4", I believe your going to put meat in the freezer.
Though I was wondering a little bit of the effect of driving the gun back and forth to camp. I have it in padded hard case or sometimes soft case between the backseat when folded. So it may have some miles on it, between sight in and season.
I have a folder on my phone, and I take pics of target too, with notes on target you can read.
