Winchester Staball HD Load Data

[Old Rooster]

I have noticed there is no data for 180 gr or lighter bullets.
Any ideas on why?Maybe not a great idea?180 gr is just a little bit under the 190 gr load data so I may reduce by 5 percent and try just for kicks and giggles.

I talked to Winchester this am and asked why there wasn't any data for the lighter bullets and the response was…it is usually an indication the powder is too slow for that bullet and the given case capacity.
FYI: I asked when there would be data for the 257B, 270B, and 340 Weatherby's. They said their test barrels for those Weatherbys were shot out and they would test those when they had new test barrels. They currently have the 257 Weatherby test barrel on order. There is data posted on their site for the 6.5 RPM and I will be doing load development on it in the future. I would like to start development for my 257B and 270B but will have to figure out a safe starting point. I don't know if the updated version of Quickload has the HD data yet.
I will also post additional info / data when I have it available.

I figured there had to be a reason.
Thanks Duane

Powder Valley currently has both 1 lb and 8 lb of Staball HD. Shootingbot.com list a promo for PV of PV150SB and PV250SB for $25 and $50 off respectively. The second code worked for me when I bought some along with some H4350.

You might find this interesting. It is from another thread where the question was asked what is the Ba, burn rate in QL for Staball HD?

Got some interesting thoughts on that and the reason it has been developed by Winchester with Hodgdon.

Slower Burning Powders ranked numerically by burn rate

I do not use burn rate charts. I use updated manuals to determine the better powders to try. That works, but if you get GRT or Quickload, you can get it to spit out every powder that will work w a given bullet, a given barrel length, and what velocity you will get for every powder and every...

Not that it helps in the Staball HD discussion, but the latest iteration of Quickload updates (which can now be downloaded instead of snail mail, for a more modest $15 or so in USA) DOES finally have Staball 6.5 data...

I just got my update disk dated 2023 and it did NOT have
Staball HD? Is your disk dated later?

Read my post again. I did not say that Staball HD was nin the latest Quickload. I probably should not have posted to avoid confusion, but I am interested in the Staball line generally, so was reading the thread. Only 6.5 is the latest iteration of Quickload.

Yes, I misinderstood your post, and see now all you were saying is QL now has Stsball 6.5.

I finally got some HD to test, but I hit pressure way earlier than I was hoping for.
I use GRT and Staball HD was around 25fps faster than my Ramshot Magnum profile. If you have a Ramshot Magnum profile in QL you could try some low pressure loads with Magnum and work up from there.

Yes, I thought this would be close to Retumbo. So, that makes sense.

Magnum is .345, Retumbo slower at .337

So, it was faster than Retumbo too.

It was based on your results between H1000 and Ramshot Magnum....

I'll have to test mine too. I bought 1 lb.

I tested Stabal-HD in my Wby Vanguard 24" 300 WM and 200gr ELD-X last May. Got this node 5.5 at 2840 fps. I guessed some parameter values in QuickLoad that were close to Retumbo and then refined those after shooting some of these loads. This is about 100 fps slower than what RL-26 does and close to the same as Retumbo or H1000. This was crummy Winchester brass too.

 

[VarmintBob]

if you want any help let me know. That load is something like 58K max psi. Pic of my not heavy bbl 300 WM.

Got the above from Winchester.
Here is the link for the 2023 Powder Burn Rate Chart:

https://hodgdon.com/wp-content/uploads/2023-burn-rate-chart.pdf

That puts Staball H D right in the sweet spot for many of us.

Hey thanks Rooster for the chart....couldn't have JUST MENTIONED IS WAS NUMBER 162 for quick reference , good have you?
