HOT vrs COLD weather bullet drop
I am trying to understand the performance change across 50 degree temp change.
Two months ago I zero'd my 308 at 100 yards. It was near 100 degrees here. 3 shot group was 0.383 MOA.
This morning it was 48 degrees. FIFTY degrees cooler.
100 yard result was nearly 2" HIGH. SAME AMMO. Same everything.
200 yards was near 2" LOW from the 100 degree results.
Tikka 308, 1/11 twist, 22.4" bbl
Sand bags fore and aft.
Vortex FFP 4x16x44
Remington Corelokt TIPPED Boat tail - 150 gr
Anyone have an explanation for me?
Thank you!
