Best of luck to you personally!
The impact of temperature on barrel and bullet diameters would be an conversation outcome involving rifle and ammunition.
As most reloaders know, there are powder weights that deliver both precision and very low SDEV but will also weights that make a person or the opposite. When ES/SDEV are not consistent, they have a tendency to distort the standard MV measured. Just puzzled if this afflicted the final results posted.
The shooter is just about generally the weakest hyperlink, and that means you’ll get probably the most return by expending time and Vitality there. Here is what I’d advise to any new shooter:
From from “Precision and Precision For Extensive Array Shooting”/ p 86. “Ir’s not unusual for rifles to hit unique POI determined by the velocity of your load due to harmonics, that happen to be unpredictable” But no comment on magnitude from the outcome as being a operate of temperature.
I attempted to track down the post with the charts and shots but no results. The posting appeared on A further web-site but in addition with neither charts nor photographs.

but when you finally are outside of that place if gains and looses velocity. Testing reveals factors ar enot linear for many powders , some have selected temp ranges where by practically nothing Considerably takes place and after that a steep fall or climb ,you may avrage that but its not true.
If you only study 1 post With this series, Allow it to be THIS 1! This short article requires all the info collected over months of Are living-hearth study and sums everything up by ranking Just about every kind of ammo by strike chance from 400 to one,200 yards! In any case, the dimensions of a group on paper at a hundred yards or even the muzzle velocity our chronograph spits out doesn’t actually make any difference – a minimum of in a roundabout way.
