This article is Part 5 of our series on reloading the .308 cartridge for the Palma course and other long-range matches. In Part 1, we discussed various bullet choices and the sometimes tedious process of real-life load testing with its inherent limitations. In Part 2 we introduced the basic problem with the .308 at 1000 yards - keeping it above 1.2 mach - and covered my thoughts on component selection and brass preparation for the .308. Part 3 of the series cautioned against simply copying another shooter's load, presented the techniques for determining the minimum MV necessary to remain above 1.2 mach, and showed range reloading as a useful method of reaching that MV safely. In Part 4 we focused on pressure factors by showing the dramatic range of case capacity in .308 brass of different makes and also demonstrating the capacity differences caused by changes in throat length and resultant seating depth variances. If you haven't read the first four articles in the series, I urge you to do so as they provide the background for this final installment.
