Think you have a MOA or half MOA hunting rifle, I will bet that you don't. I am sure that is going to ruffle a lot of feathers but take the following challenge and report back on this thread. Take your favorite hunting rifle, not 16 lb chassis stocked rifle suitable for PRS competition but something actually reasonable to take to the field. Carefully zero at 100yds. Let the barrel cool and put up another target and fire 1 round. Save this target. Over the next several months go to the range 10 times. Put up this same target and fire one round, no checking zero first, changing sight settings ect., your first shot from a cold barrel. No picking perfect days to go to the range, wind/weather wise either. Also try to pick a time of year where the weather varies a bit. Put this rifle up only one shot per range day, bring something else to shoot. You also can not fire all your rounds off the bench with sandbags. Prone over your daypack, prone/sitting w/bipod or any other field position for 5 shots. The other 5 you can use the bench though I have never found one in the hunting fields. No called fliers or other excuses. You can warm up first shooting another rifle if you want. I do not own such a rifle and I will bet few if any actually exist. I would venture that few exist even if all shots were fired from the bench. Putting flame suit on now!
