I got that load sheet from Berger last year when I started working with the 109s. It is VERY conservative. They didn't have the parameters they used for Quickload available when I called, but using the parameters for my rifle, my starline brass at my COAL Quickload gave me pressures in the low 40,000 psi range. Even though I'm using the 109s rather than the 105s over Varget they didn't start to come together until I was over 26 grains. Their chart lists 25 grains as max with the 105s. I'll attach some results. Note that the 25 and 25.5 grain loads were shot at 100 yards, while the 26.4 grin load was shot at 200 yards.
