6.5 Staball powder

[Ironworker]

Well W-W came out with a new ball powder tittled 6.5 Staball . They claim 30-200 FPS increase in velocity ? On their web site they post some impressive results for 22/250 and 55 gr bullet. I wonder if that same new powder can be burned in a 220 swift ?

If it turns out to be as temp stable as they are claiming, it very well could work in a wide variety of things. If it can do that, AND, provide increased velocity, what's not to like about it...

I ordered a few bottles we"ll see .

Should be great for a 223 with 90’s

I ordered some to give that a try.

You gone try it and let us know

Take a look at this:

I wonder if case fill has anything to do with temp stability? I would think this powder would be nearing compression with a 90 and a 169 freebore chamber.

I wondered that myself. I fill find out if there is enough room. Think my powder shows up today

Ball powders should typically take up less volume for a given charge weight than stick powders. Getting enough of this powder in the case shouldn't be an issue. My only concerns over the idea of using this powder with the .223 and 90s are pressure and velocity. We don't need any more of either. I could shred bullet jackets and kill the primer pockets in a single firing with H4895 if I wanted to. The usefulness of this powder for that very specific application is going to depend on where it wants to tune in terms of velocity. Somewhere in the 2800 to 2820 fps range out of a 30" barrel would be just about perfect. If the nodes are well below and above that (i.e. ~2775 fps and ~2900 fps), then it really won't be any more useful than the powders we already have, IMO.

Granted Hodgdon's OAL are short but they do show a compressed load with their max load in 223 and 90 smk. The temp sensitivity shown in the video is poorer than I had hoped for too.

My comment above was aimed at loading 90 VLDs to a COAL of at least 2.630". No reloading data for 90 gr .224" bullets in a manual is going to show anywhere near the charge weight that can be used in a rifle with the appropriate freebore for 90 gr bullets, because they all load to mag-length COAL (2.260"). With 0.169"+ freebore, my COALs typically range from ~2.630 to over 2.660" with various 90-ish gr bullets. Obviously, I single-feed these rounds. With a 90 VLD, loading to COAL means as much as 0.37" worth of bullet shank sunk below the neck/shoulder junction. That's a lot of boiler room to be giving up. Frankly, I wouldn't even try to load 90s in a rifle that didn't have a very long freebore. That's not to say it can't be done, but it means giving up so much effective case volume and ultimately, velocity, that much the advantage of the 90 VLD's BC is lost. For loading to mag length, bullets in the 70-77 gr range are a much better option in .223 Rem.

Well slow pour i came up with 30gr of Staball 6.5 to neck shoulder junction in LC brass don't recall production year. Just need to find some time now to load and test some to see what velocities i can get.

30 gr under a 90 VLD ought to just about do it .



James, have you looked at the other thread about this new powder with the link to a video detailing a temperature/velocity test? If you haven't seen it, it's worth a look. It seems as though the temperature stability of the Staball powder isn't quite as good as the best single base powders, such as Varget and H4350, but it's much better than the average double base powder.

Yes I have. A lot disappointed in the temperature sensitivity but I'm currently using RE17 and the Staball seems to be an improvement over that. Can't get enough RE16 or H4350 in the case to equal performance of RE17 so that's why I'm looking at Staball. Thank you for the heads up though.

I ordered powder yesterday and forgot to get a couple lbs of this to try.
