vv 100 series powders on 150-170

[ARlife4me]

being that the flame temp is low compared to 500 series. with the 100's giving less velocity than wanting (some up to 150fps slower) i'm trying to decide on what cartridge to use to get the needed space for the extra fps? i bought 150, 160 & 165 so far and wondering what cartridge and bullet combo you have had success with?

cartridges i have that would possibly be used in
243win
260rem
6.5prc
270rem
7-08rem
7saum
300wm
338lm

maybe in 264wm also

The only side by side comparison of 100 vs 500 series I ran was in 300WM with 196HH. Max safe load in my rifle with 165 was 76 grains at 2875 fps compared to 77 grains of 560 at 3053 fps. This is from a 22" barrel running suppressed. Since both loads were compressed, there was no additional case capacity to be had with 165 vs 560. However, a quick look at QL shows that 150 and 160 can reach max pressures in the 300WM at load densities in the 92-95% range.
