[QUOTE="DocUSMCRetired, post: 1011907, member: 85458"] To calm down some of the arguing with scientific fact. I did read the date on how long ago the last post was, but I wanted to provide some scientific input. Fact an increase in temp causes the nitro cellulose based powder to burn at a faster rate. This causes a change in impact that is 4 times what simply air temp change alone causes. Of course not all powders are effected the same. This change in powder temperature will change your muzzle velocity, some more than others as some powders are more stable. Changing muzzle velocity will always change your ballistic curve. How to over come this is easy. Our software allows you to calibrate for this change in muzzle velocity by inputting the different muzzle velocities you get at different temperatures, then it builds a solution for you based on this. Effectively helping to calibrate your ballistic curve. Applied Ballistics Support Staff [email]doc.beech@appliedballisticsllc.com[/email] [/QUOTE]
