Kind of on the same note, if you make any sort of scope adjustment on the turrets, just take a sighter. Too many times I see people make an adjustment on the windage knob and then keep shooting for record. We are all human and dialing the wrong way happens a ton.
Full relaxation behind your rifle takes at least 5 minutes. That in itself will halve your group size. The platform you shoot off should be "dead", devoid of vibration. So no truck bonnet, wood pallet, or plastic fold out table. I love to get perfect zero with a tested ammo on a calm day/perfect conditions. Then take notes. From then on any shifts are the conditions of the day to work to, with a reliable reference for the use of. Each time out builds a practical history to further build the practical picture for future reference. Ha ho, all good fun.
Good points, but I haven't seen that many mirages in Canada LOL!!! Breath and squeeze is how I show some folks to attain better accuracy , especially new shooters .Cheers!!
Yes where I am from it is always hot and humid which makes the air like a soup. That is a great tip and new shooters really need to slow down and take the time with trigger control
