22 Creedmoor and 6.5 Staball failed today

[Ironworker]

I'm thinking about trying N550? I've tried Re#15.5 and H4350. I guess I can re-visit those. the SD were too high with the 6.5 Staball. My rifle has a 26" 8"twist bbl. These loads will be for Wyoming Prairie Dogs

StaBall 65 is, the Best Powder I use, in my 6 XC ( 107 gr. SMK's & 108 gr. Elite Hunters ) and in 65 Creedmoor with, 130's and 143' gr Eld's. ( Probably Not a good Powder with, Light Bullets / Small cases )
Question; ARE you using,.. "Small Rifle",. Primers ??
Large, F-210 M Primers Lite StaBall 65, off,.. REAL,."Well" for, Me.
PS;.. the 62 gr. ELD-VT is,.. a REAL,.."Fussy", Bullet,.. in "Some" Barrels ( I've Read ).
Good Luck with,.. your Tests ! Maybe Urban Rifleman will,.. "Check in", as he's Familiar with, THAT Bullet.
For Sage Rats and PD's I use, 50 V-Maxes and 55-60 gr. Nosler Bal Tip's, in a .22-250 Rem. with Fast burning Powders like, H-4895, IMR 4895 and Lately,.. IMR 8208xbr,
In my .22-250 w/ a 69 grain Bullet I use,.. IMR 4350

I had no luck either with the slower powders in my 22-250ai
Everything was better around the 4350 area

Ironworker -

Howdy !

IF you can’t get WW760/H414 ( and that powder is going away ), a possible powder to try would be Hybrid 100V. It is ranked right next to 6.5StaBal on Hodgdon’s powder burn rate chart as being just a tad faster “ burn “ rate than 6.5 StaBal.

Apples and near apples:
My wildcat “ .22-35 Remington “ has case capacity of 49.4gr H2O.
Shooting 75 “ A “- Max in my “ .22-35Remington “ wildcat rifle w/ a 28” SS 1-8 K&P,
my best accuracy/field load of 40.5gr AA3100 gave 3,420fps ave, when shooting FED LR Match. A switch in the load to FED Large Magnum Rifle Match gave 3,500fps ave, with a slight opening up in grouping.

From a 24” barrel, WW760/H414 gave me the best accuracy when shooting 55-63gr
.224” cal bullets. * VV160 gave me higher vel than WW760 did, and almost as good accuracy. For all of those loads, FED GM-215M worked superbly.

Note:
Kaltron-Pettibone once told me that the high energy VV5XX series of powders were intended for use in-association w/ heavy for caliber bullets. The 62ELD-VT is more of a medium wt .224” cal offering, when things like 75-90gr bullets are offered in that calibre.
In testing my loads/my gun, VV560 was down on vel and obtainable accuracy under .224” cal 55s through custom .75” long 60gr HPs… which was consistent w/ what the VV powder supplier said. That puts suitability of VV550 powder under 62ELD-VTs in question. Hmmm….

My point:
IMHO…. You are on the right track as far as powder “ burn rates “ go, and the answer should lie within the H4350 - AA3100 - VV160 “ burn rate “ span.

With regards,

SDs could be high because you are using light for Caliber/ Cartridge bullets. You might find that 75gr. ELDM bullets, and Stabal 6.5 ( or any heavier bullet up to 88gr. ELDMs ) will bring down your SD. My personal rifle ( Shilen 1-8 twist) had higher SDs (35-42) with lighter bullets. I found that with the length of the throat, lighter ( shorter bullets) required me to seat my bullets out so far in the case that the crimp wasn't tight enough to allow for low SDs. With my rifles preferred load (75gr. ELDM, 41 grs. Stabal 6.5, CCI LRP) my SDs are 9. It isn't the fastest load but at 3348 fps, it's plenty fast enough. And average groups are in the .2s.

 

[Ironworker]

Thanks everyone. I'm going to start loading 75-77 gr bullets.

 

[Woollybugger]

In cold weather I struggled with 6.5 staball in small primer (cci 450) GT brass. Hang fires. I gave up on ball powders in cold winter. Reloder 17 and 70-80gr in the GT are very dependable.

 

[jds holler]

Might be that a single base powder might be better for your barrel shooting PDs in volume.? jd

Good Choice of Bullets w/ StaBall 65 powder !
Use CCI Small Rifle, Magnum Primers to, Lite off,.. Ball Powders ! ( CCi 450 ??,.. i think )
I use F-210 M's here, in Idaho w/ StaBall 65 and NEVER,.. any issues !
My 2 Rifles LIKE, near Max charges of, StaBall 65.
Gary in Md. is using, 39.0 grains of StaBall 65 in his Tikka 22" 1-8 Twist, .22-250 Rem, w/ 77 gr. TMK's and LIKING, it ! 3,250 FPS w/ F-210 M primers and a COAL of, 2.525 inches ( For, a .22-250 Rem ).
He didn't state just HOW "Accurate", the Load was, tho.
I'm assuming it's, pretty "Good" or, he wouldn't,.. Use it.
You "Might" start there and "Work Up",... carefully

 

[Ironworker]

My 22 CM brass is all large rifle.

 

[jds holler]

I've been loving the Staball 6.5. Bout to start a load for 243 with it. So far I've just done 6.5 CM, and 7-08. Both were easy peasy for good accuracy and velocity. jd

 

[mic2377]

I have had inconsistent SD's from ball powders in general, but especially ball powders loaded below max or those with ignition issues. It seems stuff like Staball needs to have a good case fill and higher pressures to have a hope for good SD. But sometimes it still doesn't deliver.

If you want to try a few more loads with Staball maybe a you could try a magnum primer?

That being said I love the N5** series powders. I shoot N560 under 80's in my 22 Creed and right from the get go it delivered very good accuracy and single digit SD's. I haven't shot any N550 in mine, just N560, so I can't comment on specific load data to help.

I have a bunch of N560,I'll try it. I wonder how a Berger 80.5 Full Bore will do on Prairie Dogs?

 

[Eagle1899]

I use Staball 6.5 in a few cartridges. As a rule Small Primer brass gets a CCI450. As mentioned before it favors a full case, near max or max loads. No issues getting single digit SDs.

 

[Idaho-Lefty]

My 22 CM brass is all large rifle.

Hogdon uses, Lge Rifle, F-210-Match pr's with, MOST of, the StaBall 65 Loading's,.. that, I've seen.
I'll be using Gary in Md. .22-250 load, w/ 39.0 grs of, StaBall 65, F-210-M's and, the 77 TMK's after I, "Burn Thru" most of, my IMR 4350 and 300 of, the 69 gr. SMK's, first.
LOL,. Probably Be, next Winter, before I get to that, Load.

N-560 with 85.5s in mine too. 560 worked best with 80 and up. 26” 7tw Krieger. Also shot N555 with 77tmks really well in same barrel and a 22” ibi carbon 7tw. Wanted higher bc in heavier gun than tmk. When I got carbon barrel gun together took the 77tmk with 555 ammo to break barrel in and zero. It just hammered em in a ragged hole. First group after getting it zeroed was .198 with load for a different rifle. Nice to get lucky sometimes. Never changed load, still shooting the same after 400rds. Tmk’s will open critters up. That is the truck gun and does the most critter killing.

Now it's settled N555 behind 77gr TMK. Mybbl is 26" Muller works 8"twist

A Note for, any of, the Newbie's that, "may Read",.. the Title,..
The StaBall 65 gun Powder, did NOT,.. Fail,..
the OP used, the WRONG Bullet ( too Light of, weight and a "Fussy" one ) with, the AWESOME, StaBall Powder.
Heavier, Longer for Cal, High BC, bullets, Shoot "BugHole's" for Me, with StaBall 65 Powder at, close to,..
Max Charges.
All you StaBall, "Haters" send Me your un-used Gun Powder and,.. I'll Dispose of, It,.. "Properly"
