Found one pound today, along with some H4350 and MR2000, all of which I had struck out on elsewhere.

The Hodgdon data shows workable velocities in my 6CM with most bullets even at starting levels, a good thing I think.

I’m eager for load data for the 257 Roberts with this powder. I went to the range yesterday with some 06 loads with StaBall and was pleased with preliminary results. Anyone with reliable Roberts data please post it

Would like to see that myself.

It'll have to perform to beat H-100V in the Roberts with 100's. Mine shoots the 100 TTSX at 3,266 into sub inch groups. That's pushing 25-06 data. And with no pressure signs. StaBALL should be more temp stable than H-100V.

Great shooting with that Bob! I've got staball and I'm wanting to try it in the 250 Savage and looking for some load data.

Load data for StaBALL is pretty close to H-4350. I'm wondering if one used that data, starting loads, working up with a Chrono.

StayBall is slower than H4350.

I'm developing loads with it in a couple 22 Creeds, and a couple 6 Creeds.

If it's slower, then won't H-4350 data be safe as a start?

Look forward to your results.

That'll work.

Temp sensitivity testing will be a work in progress. Summer should get here sometime in August..;)

If you look at published Hodgdon data where StaBALL and H-4350 are both used, the load data is pretty close to the same. Examples are 6.5 CM and 7-08.

Dirtfarmer,

Hell, I got 3250+ with IMR4350 and 100-grain bullets in the .257 Roberts over 30 years ago, with ZERO pressure signs!

Just had to throw that in. :-)

If this has been brought up I apologize for repeating it, but the April Handloader has an article on StaBALL 6.5 by Rob Behr. In it he claims it is slower than H4350 and faster than H4831 and near Hybrid 100V.

Well that's almost 3,266 fps... cool

257 R is indeed a great round. And, as I think you've written, a 100 gr. bullet is probably optimal.

48 gr H-100V with the 100 TTSX topped 3,300 fps, but at the cost of some accuracy. And still with no pressure signs.

47 gr seemed to be the magic load and the one I went with.

LA 700 with 24” Brux. Long action allows longer COAL and slightly more case capacity. But these are not compressed loads to begin with, so not an issue.

DF,

It probably was just about 3266 fps--since the load was chronographed with one of those old-fashioned light-screen models, place 15 feet from the muzzle! (Also got around 3300 with 100-grain Hornady Interlocks using the same powder, but they don't result in as much pressure.)

Of course, I am pretty sure those loads exceeded today's +P data!

Hi!


Just an update on my experience with STABALL 6.5

To date, I’ve tried it in the 8X57, 30-06, 6.5X55, .308 Winchester.


From my experiments: This powder definitely seems to have a burn rate closer to IMR4831, than to IMR4350. (in my rifles that I tested it in, it seemed to have a burn rate just like IMR4831)

However, my suggestion is to follow the advice of the manuals, and treat it like IMR4350..... but back off about 5 or 10 percent and start from there.


I did NOT chronograph the loads but the power of the loads seemed to be comparable to my hunting loads using IMR4831, IMR4350, RL-19, RL-22, and finally IMR 4955.

BUT in most cases, I got the best accuracies with this new powder. (STABALL6.5 Powder)

6.5X55 Model 70: 43 grs. STABALL best accuracy!
Roughly 1/4” to 3/8” groups at 50 yards using Hornady SST 129 grs.

BTW..... a 46 grs. charge was MY maximum pressure load.


308 Winchester in a Marlin XS7 Rifle (a great Rifle BTW....! I love every one that I own!)
Using a 165grs. PSP BT bullet (I believe a pulled PPU bullet), I used a charge of 52grs. charge, gave me a nice tight 5/8” group at 50 yards.
It was NOT a “high” pressure load in my rifle.
Maybe about a 2650 FPS? A good hunting load.


30-06 in a Savage M110 Rifle: using a Speer 150 grs. PSP Hotcore bullet (my “go to” deer bullet in most of my 30 caliber rifles)..... with a charge of STABALL of: 60grs. gave me a near max load in that Savage rifle. It was the most accurate load tested that day. (about 45 Fahrenheit). Groups of about 3/4” to 1” groups at 50 yards.



8X57mm Rifle: A Yugoslavian M98 ( a “Butchered” or “Beater” job..... call it someone’s version of a Sporter. Too bad.... you don’t find many of those around!)
Treating it’s loads using Speer 150 grs. PSP and Hornady 150 grs. PSP bullets, like the similar IMR 4831 powder.... the STABALL powder generally performed at least as accurate as the IMR4831 loads, and generally the best accurate loads.
I tried charge weights of STABALL of: 55 grs., 56 grs., 57 grs., and finally 58 grs., with the 150 grs. Bullets.
ALL those loads proved to be more accurate than my hunting load using IMR 4064 powder (48
I’m guessing the velocities to be between 2500 FPS. to maybe about 2700 FPS. or so....).
All usable loads and accurate.
Pressures? Reasonably high... higher than US factory loads, but not quite max.
Sub inch groups at 50 yards.


But all this is to show how this new STABALL powder was not only comparable to the burn rate of IMR4831 (and even IMR 4955), but also just as accurate also. In fact in most cases, I’d say that STABALL powder over all gave me the most accurate loads tested, with any of those other powders.

So I plan on stocking up on more of this powder!
It really seems to be one of the best!
But I’m not going to stop using IMR 4831 or RL-22 powders, either.
They have always have been among my most favorite powders in many of my rifles.

It is obvious that I am NOT a great shot, which is one reason why I don’t shoot much at 100 or 200 yards. Lazy? Yeah.... I guess so. But generally I am satisfied with my accuracy tests at 50 yards.
If I need tp do it, then I test at 100 yards and sometimes at 200 yards. But generally it’s not necessary.
It IS necessary for me to test/sight in my rifles, right before Big Game season. In those situations, then I do shoot at 100 yards.

So yeah.... I’m lazy!



So for all interested, I suggest to try a pound of this STABALL and give it a try in your rifle, if it’s burn rate in appropriate in your rifle’s caliber.
It seems to be (so far....), everything they say it is.


Having a clean burning powder that is temperature tolerant, that compacts easily in a small case, with a burn rate similar to IMR 4350 to IMR 4831, is a VERY useable powder.
It not only seems to work well in smaller cartridge cases like the 243/308, but seems to work in other cases in size from 7X57 and 8X57 Mausers, but also those as large as the 270/30-06 case size too.

Eventually I’ll try it in the larger belted magnum cases too.
It should work in my 308 and 358 Norma Magnum rifles as well as in a 338 Win mag that I also have somewhere.
I’d guess that it would work well in the WSM cases too. (maybe also in the 300 Winchester)
It also may work well in a 375 H&H Magnum.



So I have my work cut out for me this year!

I've been testing it in 6.5 Creed, and 270 Win. Very small groups, and single digit SD numbers all around. Very, very consistently accurate loads, all the way from start to about 1.5-2 grains over book max. Not a velocity king like R26 or R17, but much better groups in those 2 guns. Both shot well under 1/2" at 100 yards. Definitely going to try it in my .338 WM next.

I'd be interested to see some of your 6.5 Creed velocity averages, if you care to share them.

46.1 grains with a 123 Amax, 2850 fps, 3 fps SD over 10 shots. Was shooting R17 43.5 grains and 2900 fps +- depending on temp lol. 20" barrel.

I tried some hand loads in a 22-250 last weekend with StaBall and 62 grain TTSX's and 75 grain Amaxes and had vertical stringing with both loads.

Anyone else have that with StaBall? I was using Fed 210 primers. Do you like magnum primers with StaBall?

Due to wet weather, no range reports.

If I was shooting a ball powder, getting vertical stringing, I’d probably try mag primers.

Would be nice to see velocity readings with ES’s and SD’s, std vs mag primers.
