6.5 Staball- 25-06

I have not found any info on Staball 6.5 for the 25-06 at all. According to the Hodgdon 2020 Annual Manual they do not list any loads for the 25-06 with Staball for any weight of bullet. The best looking powder to me was the Hybrid 100V and H1000 for the velocity vs. pressure. I'm sure you could work up a suitable load with some math and comparing burning rates with other powders if you are into that sort of thing. I do it a lot. I also ordered a Quick Load disc today to replace my Load From A Disc program that was destroyed when the disc was crushed. Good luck in finding some info. Please let me know what you find. I have an '06 gathering dust in the safe.

After a little more research, Hybrid 100V and Staball 6.5 are listed side by side for burning rates very close to H4831SC. Beginning load for 100V is 47 gr for 117 SST Hornady vel is 2850 fps. Max load is 51 grs of 100V with a vel of 3080. I would feel safe with following this data and using Staball instead of 100V. As always check for signs of pressure and chrono if at all possible. JMHO

Just because there near the same burn rate does not mean the powder density is the same. I would not do it. Ball powders respond different than extruded.

Looking for resources or information for starting and max loads for 6.5 Staball powder and 25-06, especially 117 bullets or thereabouts. Any info appreciated!

My experience in the few cartridges I've run it in, take hybrid 100v data, subtract .5 from the max, reduce 10% and go from there careful approaching max, data needs refined for bullets like monos, I used 6.5 staball data for one cartridge and was a long way from max when I hit flattened primers and hard bolt lift.

There is data for .223, 7x57, .270, 30-06 and many more. Just curious why no go on a 25-06.

What cartridge were you working with and did you chrono the tests?

I was not using a Chrono as there was no data for a mono with 6.5 in this weight, I went a bit rogue and decided to test based on results, I have some bonded bullets coming in soon and since I'll have more of them than what's left of the monos that are already shooting well in another rifle/load, I'll reassess the staball with these new pills, if I had more monos I would have step-laddered down a few more charges since from start to pressure signs no good accuracy was found.
We were running a .22-250, it's still a good powder that I'll likely keep using, but if it doesn't like these 62 bondeds, I'll likely not waste more bore life on it as I have several other powders on hand. The .243 and .270wsm and the 7stw have no issues chewing it up.

Whats some of your other favorite powders for 25=06. I am thinking imr 4350 and H4831

My favorite for .25-06 is IMR4831. Most accurate load uses a 117 Sierra. (0.3" 3-shot groups.)

I'm a new reloader and I haven't yet loaded any 25-06 Remington cartridges but the data for IMR 8133 in the Hodgdon Annual Manual raised my eyebrows enough to purchase a 1 lb container of IMR 8133 to test.

For 117 grain (Hornady SPBT), 24" barrel, Remington 9.5 Large Rifle Primer

Start 56.2 grains 2939 fps 49.1 Kpsi
Max 61.1C grains 3216 fps 61.5 Kpsi

It's not always true,but a lot of times,ball powder isn't quite as predictable as extruded powder in my experience,especially in hotter overbore rounds like the 25-06.I can use either IMR or Hodgdon 4831 and all is well.Ball powder can be harder to ignite,and less temperature tolerant.I've seen a little something change in an individual round cause CFE-223 make a mess out of a 308 case...blown primer,pocket so stretched a primer could rattle around in it,severe change in recoil,and when the rifle ejected the brass,it was deformed from the extractor.It was an AR-10,and I still can't say what happened.It was once fired Lapua brass that was trimmed,and the charge was 2 grains under max.Maybe the bullet moved during feeding,I don't know.I've also seen some excitement from WW760 and 748,but not that bad.There must be some reason all the powder companies make extruded powders.If the small granules work so good,they would all be making ball powder because it meters so much better.
