I've got some sitting idle. When I can get to it, it'll be below an 140 gr. ELD-M in a 6.5 Creedmoor case.

I will shoot the same three loads again in the summer at around 80 degrees and then decide whether to continue.

I have been testing it in my 6.5 Creedmoor with a 143 ELD-X. Accuracy node seems to be a bit slower than H4350, I would say about 75 FPS lower in my rifle. There is room to go up, but not enough room to catch the next node.

So you were complaining and harrassing Chad just for the fun of it?

Heck, you could have an 80-degree day to shoot rhat load in the next two weeks. You never know in Texas!

I shot my 6.5 CM test loads Tuesday when it was in the upper 30's. The starting charge of 4451 was the same charge weight I stopped at in the summer time. In the summer, that same powder charge ran 2720 fps, and Tuesday ran 2782 fps avg. Same everything, just ammo loaded a different time.

Shipped wet??? I've never heard of anything like that in reference to powder. Please explain.

I'm not positive myself, but I'd go out on a limb and speculate that it means "wet" with solvents that have not completely evaporated. There may not be "much" in there, but what is in there adds a little mass.

4451 recipe's??

That's very interesting. Yes, I guess it could be solvent. I have noticed that sometimes a new container of powder opened for the first time can have a stronger odor (solvent?) than one that has been in use for a while.

I have always tried to keep my powder closed tightly so it won't absorb moisture (water vapor.) I presume it has some level of moisture in it when I buy it. Keeping it closed helps keep the moisture level more constant.

If the solvent evaporates with time, then each kernel of powder becomes lighter in weight. Then we get more kernels for each grain of powder. Does that create more fire, more pressure, more velocity per grain? dee, have you ever tested exact same loads using "wet" vs "dry" powder?
