From from “Accuracy and Precision For Extensive Vary Capturing”/ p 86. “Ir’s not uncommon for rifles to strike different POI according to the velocity with the load resulting from harmonics, which might be unpredictable” But no comment on magnitude from the result as being a purpose of temperature.

You’ll want to take a look at our to start with Tale In this particular two-element collection covering loading 7mm Rem Mag with Budget Lyman reloading products!
