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.

I've used 160 in 22-250's with 9 twist barrels and heavier bullets (60gr BT and 75gr match hp) with success. One rifle liked the 60's better at 3500, the other liked the 75's. Have used it in a 270 with 145's, shot well just slow, under 2800 with 24' barrel. 7 mag with 140's is the next project

What difference will 150 fps make? Just curious

N150 works well in 7mm-08 & 7mm-08AI.

Once you start going over bore on like the 243 Win, they like the slower burning powder with heavier bullets.
I was using RL26 with 100 & 105gr bullets in my wife's 243.

I've shot 44 grains of 160 with 140 sst for years in my.260. I tried 560 but it wasn't any faster or accurate. So I couldn't justify the cost difference. That is with a 26" barrel. I tried 560 in my 300 wsm and 200 grain eldx and velocity was comparable with hybrid 100v and h4350.

They have a lot of good data on their website. They are usually pretty accurate on charge weights
