I am done banned for life on that site, or until I can get a new IP address. But in QL, isn't that the BA number? The kg/kj outside temp factor.
You can pull these numbers from quickload and use it in the excel barrel life calculator. You can download it here:
Looking at other ball powders I’d estimate it to be around 3800 kJ/kg or so, but it’s hard to say exactly.

Sorry for the interruption, doubt I'll be trying staball

Lol, oh fuck, I failed to comprehend the number could be on the right side of column, I will STFU.The energy density / heat potential of the powder is the first number. BA has more to do with how slow / fast it burns. The temperature function in QL was based on an old study of temp sensitivity, but does not apply to modern powders like Hodgdons extreme series or Alliant / Bofors line of TZ powders like AR Comp, RL16, or RL23.
Im also not super convinced StaBall is going to be a game changer, but I could be wrong. I just want to know the specifics so I can see how easy or hard it might be on a barrel relatively speaking.
Good report, looks like you found a repeatable sweet spot. If the next time out gives the confirmation you're looking for, you can perhaps tweak seating depth to reduce group size even more. I'll look for additional updates. Thanks!Here are the results...
42.9 Gr. 2,609 MV 12.3 SD
43.2 Gr. 2,634 MV 15.6 SD
43.5 Gr. 2,657 MV 11.9 SD
43.8 Gr. 2,706 MV 14.3 SD
44.0 Gr. 2,728 MV 11.2 SD
44.3 Gr. 2,737 MV 8.1 SD
44.6 Gr. 2,763 MV 4.1 SD
44.8 Gr. 2,784 MV 7.8 SD
45.0 Gr. 2,811 MV SD skewed due to an error ES @ 45.0 was 26 FPS.
Stopped due time, have 20 rounds loaded at 44.6 Gr. and going to run these tomorrow. Going to get a 20 shot string to capture accurate SD & ES
All above shot at 300 yds from my MRAD 6.5 with bipod and mono, the best group was the 44.6 at 1.3” Surprisingly all loads group really good, OCW was 44 to 44.8 all about 1.5” high and 1” right...
The temp was 54* ammo at ambient temps, bolt opened to cool for 3 minutes between shots.
No signs of pressure issues...
FYI 41.6 Gr. H4350 MV @ 2,752 SD 3.6. The gun likes 2,750’ish MV.
I assume you were attempting to run this is a creedmoor sized cartridge? If so you won’t see decent ES/SD until you get closer case fill.Sticking with H4350.
7 1/2 pounds staball gonna be for sale.
Right, ??Remember that time Varget and H4350 were finicky? Me either lol.
The way I see it, it's got a purpose for a automated press to crank out lots of 6.5cm training/practice rounds like a lot of us do with .223.
Remember when you started doing that with H4350 or Varget? Me neither, cause you cant...
I think guys are making the mistake of comparing this to their stick powder loads and the performance in relation to equal charge weights. If that's what your doing your going to be disappointed.
It's a brand new powder and meters awesome out of a 650. It will require more powder to get near max case fill to see the speeds and SD's we want. Gotta do a pressure test up till you find pressure than do a fine tuned OCW below 1.5-2gr below that and find your node. Seating depth test after that and we will see where it stands.
If it pans out, loading 6.5cm from A to Z on my 650 will be great.
I don't recall the marketing materials saying "This powder performs marginal at best but meters great in a progressive press". In fact, this thread indicates the exact opposite. It's a ball powder that performs exactly like a ball powder, disappointment and all
The tests are out? it performs marginal at best? Lolol. Please.share them? I havent seen anything definitive yet
Have you figured out a 6.5 bullet feeder for your 650?
Double Alpha sells a 6.5x55 bullet feeder conversion kit. But it's out of stock. I'm exploring the idea of setting mine up for 6GT or BR. If StaBall doesn't prove out I could still probably run a pretty good load of 8208 in a BR. It's the bullet feeder that I don't have a solution for right now

Woah! That's smoking for a DTAC in a Dasher.
Are the Dtacs coated?Lol yeah I got scared. There was no bolt lift and primers looked pretty good. Maybe just a little bit of flow around the firing pin, but wasn't flattened at all. Idk if maybe the slower powder helped with pressure or what. There was another guy that tried it in a dasher with 105s in norma brass and got pressure at 39.5. Norma brass usually has a little less capacity as I'm sure your aware of. I would like to see what quickload has to say pressure is for that load. ? I'm planning on using my dillon so dont really wanna be on the edge anyway.
Seems like there is some more velocity to get there?6 GT 24" Proof 1:7.5"

Well that disappointing, I have a 28” 7.5tw that will be cut to 24” proof comp contour. And a stock waiting on an action, and also have 8lbs of staball, what hoping to see it around 3150 with 105’s. I guess I have to stir up some varget somehow see if it does any betterNot much. 40.4 is about 100% case fill. Regardless, it shoots better at 2967
15-1700 is ok with me I guess. Barrels are the cheap part of this thing we do. Especially with the quality of prefits that are out nowI haven't shot any Varget yet (really don't want to), but my guess is that 3150 is going to be a tall order, and even if you do hit that number it's going to be short barrel life and high pressure. 3150 in a 6 Creed is a recipe for a 1500rd barrel.
My findings with Staball in my new 6 GT are that it is dirty but cleans very easily.
It likes to be near capacity in case fill.
I've been breaking in my 6GT barrel with it and various bullets in the 105 weight and am happy with it so far.
I have not pushed it hard yet.
39 grains under 107 SMK is getting me 2940 fps and 12 SD for 10 rounds. This is with 130 rounds on a new Bartlein 7.5 twist 5R 26" barrel out of new Hornady brass.
I’ve found that as long as I keep with a 7tw bart it stays pretty even one ladder and your done. With good notes of where you started at least. But I get what your saying. But how long do you normally get out of a 6mm creed or 47? 2k? 2200? Or are you getting way better than that.Sure. If that's your thing. I don't hate it. But I guess I appreciate the consistency of a barrel that lasts longer because along with that you get longer stretches of good performance with less tuning and less barrel to rebarrel transition, break in, and load D.
I was hoping to get 3150 with a gt and 105’s yes. My 6creed runs 3130. Sorry for the confusion. And I expect 15-1700 barrel life in my 6 creed. I’m waiting on the action for my 6gtIn your previous post, are you talking about getting 3150 from a GT? That's what I assumed. A 6 Creed? So far, 1800. With usually a tune-up at around 800 - 1000rds, another tune up around 1400 and then doneski around 1800 - 2000. If you back that process up to 1500 and compress those tune ups because of a faster eroding throat you will have fewer matches with consistency.

2978 for the 115'sAlmost exclusively matches. What speed were you running?
You are hoping the GT runs faster than the Creedmoor? I'm not sure that will be the outcome, at least without pushing it pretty hard.I was hoping to get 3150 with a gt and 105’s yes. My 6creed runs 3130.
No but I thought it would be closer with lighter 105’s to be honest. Idk why I thought 108-115 would be right at or over 3000. Maybe I saw it advertised as such. Either way I’m already invested in brass, dies, barrel, etcYou are hoping the GT runs faster than the Creedmoor? I'm not sure that will be the outcome, at least without pushing it pretty hard.
With 115’s though? And my 6creed has a 22” barrel and that 3130 was with heavier bullets than 105h’s. It didn’t seem very hot at all, but I hear people finding 6 creed nodes at 2900 with 105’s and I think to myself why have a caliber and run it way under its potential. That’s the point with 6mm’s right, They are fast! That’s what we like about about them right?You'll be right or over 3000. I think guys are commenting based on the 3150 number you stated above. You'll have no problem doing 3050 with 105s
I just did load Dev for a buddy's 6.5 CM Tikka CTR using StaBall. Shot just over third-moa at 300yds. Hit a node of low velocity increase between 44.5gr and 45.5gr. Using metered/ trickled loads on an A&D I got SDs of 2. Ordered a Redding BR-30 and mounted it to a powder die on my 550. Tested the accuracy of charge; averaged about .12grs. This afternoon we hit the range to compare trickled charges and thrown charges. The thrown charge shot an SD of 3 and grouped oh so slightly better than the trickled charge.
Given the velocity increase during a ladder a .12 ES should net about a 8fps velocity difference. I figured it could fall inside the white noise of normal SD's or it could double it. Not really sure I got my answer since I'm loading in a flat spot/ node.
Either way, I'm about to load 500rds for him progressively, throwing powder. Going to time myself per 100rds. Using bulk count Hornady brass and 140 ELDMs from Midsouth, shooting 6BR like SD's and groups at 300 just a tad larger than my Dasher. Pretty cool production
140's at 2800fps from a factory 24" Tikka CTR.
It's a 24 inch barrel. It's really, really slow.Is that a 20" barrel. We were hitting 2800 at 45.3gr. I shot all the way up to 46.5 without pressure. I agree StaBall seems to be slower than 4350 in the 3 cartridges I tested it in
I checked just now and 100% case fill would be 48.88 grains for this bullet. So 93% should be right around 45.5.Is that a 20" barrel. We were hitting 2800 at 45.3gr. I shot all the way up to 46.5 without pressure. I agree StaBall seems to be slower than 4350 in the 3 cartridges I tested it in
From my testing, grain for grain it’s shower than 4350/rl16. The reason why I believe I can get crazy speeds is because I can get almost 5 more grains of staball into the case vs 4350 which makes up for the speed difference.Is it me? I am seeing mixed reports regarding velocity, some are saying higher numbers and others are saying it’s slow. What gives? I have a keg of this unopened because I am developing a load in a different rifle but as soon as I am done I will start on the ‘06 providing that I have time.
Agreed, if it's expected to be faster or even similar grain for grain, not going to happen. Charges show 4+gr higher for the Staball. A max load of 4350 is not even a starting load of Staball.From my testing, grain for grain it’s shower than 4350/rl16.
