[QUOTE="T3-OleMan, post: 719487, member: 14600"] Here is a fact from the MFG of SUPERFORMANCE POWDER!! My Nellie {338WM} likes the Hornady 185gr GMX SUPERFORMANCE factory ammo. On my shooting solution exl worksheet I have Temp as first column, 10 degree increments! Because at 70F the ammo flys at 3,080 and at Zero F it leaves at 2,997 {-83fps}I have calibrated all inf so all I need to set my scope to optimum power setting {Zeiss: rapid Z 800} is Temp - Alt - Yards to target and last but not least - Wind. Don't have any knowledge of the temp causing POI to grow but mine just drops like you would expect with speed reduction. However, I would expect, as already stated, in some cases your group could very well - in some guns- increase or decrease. Remember it's Nellie not Fred!:D Footnote: Paper never been my strong suit..:rolleyes:..Hair ....different story. [/QUOTE]
