Response to Wanderin Zero, NCed, please chime in

shoot it benched at 30 yds with NO wind

Cold and then Hot ....

POI will likely change when it is hot -

it should be a predictable change that you can note and compensate for.

A stick on temperature gauge on your scope / and or rifle will help.

Here in So Cal we often have low 60's first thing in the am and by Noon we can be up in the high 90's ...

that's a 40 degree temperature swing to account for ..... metals expand when hot ... POI changes.

It is what it is .. because it is. Good luck .... it's all part of the game .. LOL wink.gif
