Great info on load data. A bullet with a BC of 0.400 will drift over 40 inches at 700 yards in a 10 mile per hour crosswind.

Just like shooting near dawn or dusk, or shooting into a glare. This difference in bullet shape can be quantified, and the comparison simplified to one numberthe Ballistic Coefficient, or BC. Part of that preparation is understanding, in simple terms, the external ballistics of a typical long range shot. Wind Drift diagram showing how the forces act on a bullet. My prediction? 7 PRC would be a nice step down in recoil from a 300 win mag as long as you choose a lighter bullet. Max range 600yard, would like to shoot the 180s. We analyzed 6 different loads for each cartridge (the proper way to read that sentence is Jim sat at a computer for WEEKS putting data into very complicated Excel sheets) to come out with an average of what several common loads for each cartridge will accomplish. I reload and would be VERY interested in learning more about being able to use less powder to achieve higher velocities with the the same bullet in 7 PRC vs 7 rem mag. (888) 223-3006 To do load development before this speed up happens will render the load development useless. Im looking for a new elk rifle and am very excited about this new caliber. thank you.

As you can see from the above table, the 7mm PRC is most similar to the Gunwerks 7 LRM. The challenge of loading for any of the PRC cartridges is the extremely tight tolerances. Mainly, because of our inability to directly quantify wind speed and direction as we can with distance when using a rangefinder. Save my name, email, and website in this browser for the next time I comment. It seems that the cartridge was designed to compress the load right at the point where youd reach pressure with these common powders. I was hoping to optimize the cartridge .
