What was the temperature? I've been getting 2fps per degree variation with CFE on the hot side of the spectrum.Let's go Brandon! -

I've given up on it because it's sensitivity. Wasn't really so much the velocity variation as falling out of accuracy nodes due to the variation. A 20 degree temp change would make a 1/2 MOA load a 1.5 MOA load. I settled on a relatively mild XBR load for 123s at 2500 out of my 22" JP since it's the least sensitive powder you can use in Grendel. I'm interested to see your results with Benchmark. It's one of my favorite powders but usually only use it for light for caliber loads.Let's go Brandon!Comment

Several forum members like H4895 as it is a very temperature stable powder. Next time I see any H4895 I plan on buying a couple of pounds. The actual velocity at lower temperatures might prove to get faster speeds than some of the less temperature stable powders like CFE223, LeveRevolution, Accurate 2520, TAC or Winchester 748.Comment

I stopped useing cfe223 and leverevolution in favor of h4895, ar-comp and h322.
For the 123 class bullets I would try ar-comp first and if your mags and throat allow a lil longer coal length then try the h4895, it's kind of bulky and you need that lil bit of extra space to take advantage of it.Comment
