I just ordered a couple of pounds of the new StaBall 6.5 powder from Powder Valley. It has some impressive numbers for the 6.5 CM, 7-08 and similar, even good 375 H&H numbers.

I can't find any burn rate charts showing how it fits into the line up.

Does anyone know?

I saw they show 3,050fps with a 24" 7mm-08 and the 139 Hornady Interlock. That's rolling.....

Yeah, I saw that, too. Good numbers with the 6.5 CM, as well.

And reportedly temp stable with anti copper fouling properties.

I'm using Big Game in my 7-08; this one may out perform that one, which is saying something. Hope accuracy is as good.

I'm guessing burn rate is probably somewhere between Varget and BG, which is a pretty wide window. (Inquiring minds want to know)... grin
Loony minds, that is... smile

I got Powder Valley to throw in a can of Vv n-150, Nosler accuracy powder for 180's in the 338-06. I had n-140 and n-160, no n-150. Go figure.
Have 180 Weldcore to try, reportedly a very accurate bullet. 180 Combined Technology has been ordered (essentially a NBT with black coating and silver tip). Those were very accurate in a 338-284 I once had.

Their data sounds almost too good to be true.

I'm gonna try it. Chrono will tell the story as will the target. It could end up the go to powder for the Creed and 7-08. I'm not sure if Pharmseller will drop BG for StaBall, but we'll see... grin

If it's gonna beat out BG in the 7-08, it better perform as advertised.

This is a Winchester powder. Be prepared for them to drop it like so many others in the past.

Higher velocity doesn't = accuracy. I'll take accuracy every time.

Discontinued it may become, but I will bet there will never be a shortage like the ADI powders that Hodgdon's Sells.

Maybe it is accurate and fast.

Won't take long to find out.

Some of the 7-08 speeds Hodgdon is posting push the 7RM. Of course a reloader can always out run a small block 7-08 with a big block 7RM.... wink

Displacement matters.

But 120's at 3,200 fps,. 139's at 3K are definitely 7RM class. I notice that they're running StaBall at 59K psi, whereas other powders are typically around 50K or less for the 7-08. They do run 4451 at 58K. And, they're using Rem 9 1/2, mag primers, but that may be because its a ball powder.

Ya reckon StaBall has such a smooth pressure curve that they can add the extra pressure without issue. Or, is this just another way to sell a new powder.

This is an interesting development, for sure.

I should have some at my door by Thursday. I’ll be trying it in the 7-08 mostly. The numbers look impressive for 120 - 175 gr bullets. Hopefully I can find some accurate loads.

DUH !

3500 or 4000 FPS is useless unless it’s accurate enuff for your purposes.

A perfect example of this is H100V. Worst powder I've ever experienced for accuracy.

I'm a lover of loading rifle ammo on a Dillon 550. Even if velocity remains the same, a Temp-insensitive ball power is of great interest to me.

Depends on the round. Works great in my .257R, best for speed and great accuracy. Now, temp stability is not it's strong point from what I've read. Where I hunt, that's not a big deal.

COAL is too long for a SA, is in a LA 700 with Brux barrel. Check the speed. Not bad for a Roberts.

I believe you're making the mistake of directly comparing the numbers for PSI and CUP.

According to a certain regression plot (by Denton Bramwell) 50,000 CUP correlates to about 58,000 PSI.

It’s all in the same Hodgdon data site. Don’t remember them saying CUP or whatever. I was assuming equivalency.

You maybe right.

looks to be $2/pound more than the other ball powders?

Or are you comparing the price to stick powders?
