Tempreture changes in power
If you guys as I was were convinced that the hotter your rig got out in the sun, think again.
I read an article in june edition of BASC magazine regarding "boyles law".
Basically the guy had all the chronos from the Birmingham proof house plus their scales and done a test on various rifles from steyrs to daystates.
I was totally confused as none of the rifles tested from 10c - 39c, all lost power. YES LOST POWER.
If you get chance have a look im sure its on line some where.
