[QUOTE="Mike Matteson, post: 2540907, member: 101791"] This is from Bryan Litz gave his rule of thumb for how muzzle velocities may vary with temperature from different types of rifle powder. Good Double-Base Powders 1fps per degree Fahrenheit, Average Single Base Powder, 0.3 to 0.5 fps per degree degree Fahrenheit. Best Single Base Powders: 0.1 to 0.2 fps per degree Fahrenheit. 94% of shooters finishing in the top 100 in the Precision Rifle Series (PRS) choose to run one of gun powders from Hodgdon Extreme Series of powders, like H4350 and Varget. That because the Hodgdon Extreme powders will provide consistent muzzle velocities across virtually any environment. Hodgdon Extreme preform just as well at 125 degree as they do at ) degrees. SD DESCRIPTION CHART 20+fps excessive muzzle velocity variation. Not suitable for long range shooting, but ok for short range use. 15fps good factory ammunition or poor hand-loads. Useable for long range shooting but not ideal. 10fps Exceptional factory ammunition or average hand-loads. Acceptable for many long-range shooting applications. 10fps will give you approximately 1 MOA of vertical dispersion at 1000yds. 5fps Un-heard of for factory ammunition, and represents the best hand-loads. 5fps will give you approximately 1/2 MOA at 1000yds.
