StaBALL 6.5 Winchester

Winchester StaBALL 6.5

Thoughts? Heard about it a few weeks ago, someone on snipershide said PowderValley has it.

[CJW]

News to me, thanks for the heads up.

Just checked the Hogdon site for the creedmoor.

It has higher start and max loads that H4350 and Varget with higher velocities than each. Pressures vary, but all of the starting load pressures are lower for StaBALL.

It would be interesting to see if/when they have Grendel data.

Looks intresting. Anybody have some Intel on a pic of the powder itself?

Might be something worth trying with the 153 A-tip this summer from my customed grendels.

Yea I ended up seeing the pic after I posted. First time I looked the pics wouldn't come up.

I am gearing up to load Creedmoor. How much of an advantage would ball powder be over 4350?

BR:

Biggest advantage was the ball powder itself. No need to weigh out charges. Once the measure is set, charge the cases, seat bullet, and shoot.

Extruded powders. If you are shooting a rifle match, probably a good idea to weigh out each charge.

Disadvantages? The only ball powder I have used that gave me the same scores as extruded was TAC. That was many years ago and I think something was done in its manufacture and it stopped giving the same scores so I went back to extruded powders.

Ball powders normally have a greater bulk density than extruded which means they fill the case less and I prefer a case fill that goes into the shoulder of the brass. Harder to get with ball powders and maybe that is why they are not the choice of most long range competitive shooters? Also, most are double or triple base and that means harder to ignite consistently in my opinion. What does that mean? Again, X count and a point here and there.

For a Grendel though, Varget is too slow to get good velocities and 4350 is way too slow.

What little info I?ve seen makes it seem it?s a slower powder that is geared toward heavier bullets and larger case volume than Grendel. Powder Valley announced it and Winchester didn?t even mention it on their website. Hodgdon didn?t have any load data either. I?m sure this will change and data will be provided.

I?ll sit this one out and continue with 8208 until there is proven data that shows it can be successful in Grendel.

I?m sure some of you guys will play with it. I commend you on being early adopters. Unfortunately, with 3 small kids I don?t have the time to mess with a new unproven powder.

The sierra rep that mentioned it at a competition a few weeks ago, said that the temperature stability was going to be the main thing.

[Chev2500]

Hodgdon has data on their site for 18 different cartridges, .223 to 375 Ruger, no 6.5 Gr. Powder Valley has not had any in stock yet.

Just looked at the Hodgdon data. Looks slower burning than H4350. May try this velocities are pretty good but velocity and accuracy don't always coincide. Like LR1955 ball powders meter easily but as far as accuracy in my experience extruded usually is more accurate. But my barrel may hate this powder and yours love it.

No Grendel data doesn't list probably not suitable. Too slow for anything I'm gonna load for the Grendel.

Stabill is faster with smaller pills. Minimal difference with 120 grain bullets. 4350 is much faster with heavier pills in the 6.5 CM.

In the first test of this powder I've seen, Johnny compares the temperature stability and SDs against 3 others.
No load data or velocity comparisons, 6.5CM not Grendel, but first testing shows promise.
