I bought a jug of 2230S cheap some time back. I just broke it open to try with some 55 Gr bullets in .223.

At the charge weight I decided to start at it fills the case to the bottom of the shoulder. I am used to .223 charges filling the case more.

For anyone who has 2230S, is it denser than H335 etc? Is this case fill normal?

For those who use 2230 in .223, how much does it fill the case at full charge weight?

Thanks, AC

Haven't used the "S" version, but was just curious if you use the same charge weight as the 2230??

[Walkalong]

I have no data for it. Good question. I assume it is only "close".

[cfullgraf]

Since no one else has answered yet, I load 24.5 AA2230 with 55 grain bullets in 223 Remington.

As I remember, the top of the charge is in the area of the shoulder. But, it has been a while since last loaded 223 Remington and I have slept a bit since then.

[Walkalong]

For anyone interested in some very limited 2230-S data.

I loaded four well used cases (The fifth had already expired) last night with 24.5 Grs 2230-S, 55 Gr Z-Max bullets loaded to the cannelure (2.221 to 2.231), with CCI #41 primers. I had settled on that earlier in the evening, after talking myself out of trying 24.3 Grs. Should have done 24.3.

89 Degrees 39% relative humidity. (RH down from the last few days) 16" Bravo Company mid-length upper. (This barrel is faster than my Model One barrel. I haven't chronoed anything yet in my PSA 16" Middy.)

Hi=3228....Lo=3152....Avg=3176....ES=76....SD=35

A bit hotter than I want. I'm gonna try 24.3 Grs 2230-S.

The cases weighed from 91.5 to 98.0 Grs. A pretty big spread, and no doubt the cause for larger ES numbers than I would like, but this load is going to be used with mixed brass and needs to be safe in the heaviest I will use.

[cfullgraf]

Interesting. Thanks

[Walkalong]

Grabbed 10 random new used cases. (Range brass) After sizing and trimming these weighed from 91.4 to 92.7 Grs. LC11, PMC, FC. I loaded 5 of them with 24.3 Grs 2230-S

88 Degrees 45% relative humidity. 16" Bravo Company mid-length upper.

24.3 Grs 2230-S, CCI # 4 Primer, 55 Gr Z-Max bullets loaded to the cannelure (2.221 to 2.231)

Hi=3152....Lo=3044....Avg=3115....ES=108....SD=41

Blew a primer in this batch as well. (Not badly, but enough) If you want to know how to tie up an AR, get a cup and an anvil floating around in the works. :o

Still too hot, gonna try 24.0 Grs 2230-S.

I ended up going about this all backwards. Let this be a shining example of "start low and work up". *sigh*

I loaded the other 5 cases with H-322, and proved to myself once again that, IMO, H-322 is a hair too fast for .223 if you want full velocities with 55 Gr bullets.

24.0 Grs of 2230-S and 24.? Grs of N-133 are next.

I use H335, and my charge weight of 24.0 gr for a 55SPR doesn't even make it to the shoulder.

If your start charge went higher than that, how would you work up from there?

[Wildbillz]

What is the differance in 2230 and 2230-S? Is somthing added to it or removed or?? I have never seen it and just started to use AA2230 for loading some 223Rem.

Thanks

Unfortunately, Accurate doesn't list it on the "data powder" (http://www.accuratepowder.com/load-data/datapowder/) page. I suppose I could call and ask.

[NCsmitty]

Here's a two page work up using Accurate 2230-S powder, and in the text, Accurate indicated that it's 4% faster burning than 2230.
It has a min to max powder spread of 21.5 to 24 grains.

I went to bookmark that link and it turns out I had it bookmarked in a folder named "2230-S reloading Info". Silly me. No telling how long ago I found that.

It definitely seems right, 2230-S seems a little quicker than the 2230 data accurate puts out.


I reckin' I'll drop to 23.5 Grs (instead of 24.0) and try again.

[cfullgraf]

Yup. I had a similar problem recently working up some loads for my 17 Rem AR. What frustrating afternoon.

When I go out again, I plan to take a dental pick to dig the primer pieces out of the locking lug groove. (Powder was the new CFE223 using Hodgdon's data.)

[Walkalong]

Tried 23.8 Grs today. Same cases.

82 Degrees 26% relative humidity. 16" Bravo Company mid-length upper. Let the rounds and rifle warm up in the sun first.

23.8 Grs 2230-S, CCI # 4 Primer, 55 Gr Z-Max bullets loaded to the cannelure (2.221 to 2.231)

Hi=3086....Lo=3009....Avg=3058....ES=77....SD=31

Much better. I would consider this max with cases weighing 93 Grs or less, but need to re-check in 99 degree weather. Next is to try 23.3 Grs with heavier cases.

[cfullgraf]

Sounds promising.

[Walkalong]

Sure better than how I started. :o

[Walkalong]

It couldn't take the heat.

98 Degrees 29% RH.

23.7 Grs 2230-S, # 41 primer. 55 Gr Z Max.

Hi=3122...Lo=3072...Avg=3094...ES=50...SD=22

Popped 3 primers out of 5 on the 5 cases left from the 10 at 91.4 to 92.7 Grs. The others were toast.

Gonna drop to 23.4 Grs and try again in this heat. It got to 100.2 on my T-Stat (in the shade) today before I left the range.



Out of curiosity I shot my old plinker load of SRB-118 and 55 Gr FMJ's in the BCM upper and got:

Hi=3058...Lo=3003...Avg=3028...ES=55...SD=19

Then I shot the plinker load in my new Sig 556 Classic and got:

Hi=3058...Lo=2989...Avg=3017...ES=69...SD=25

Very similar velocities.

Now to prep 10 more cases for the 2230-S. :o

I ended up going about this all backwards. Let this be a shining example of "start low and work up". *sigh*Yep, *sigh* for sure.

[Walkalong]

98 Degrees 32% RH.

23.4 Grs 2230-S, # 41 primer. 55 Gr Z Max.

Hi=3093...Lo=3065...Avg=3080...ES=28...SD=14

2 primers out of 5 showed gas leakage around the primer. Still too hot.

23.0 is next. Still working the wrong direction.



My Plinker load (Load #21) that just did 3028 in 98 degree heat did 3005 at 77degrees a couple of months ago. It appears to be less temperature sensitive than 2230-S so far, but I have been to hot with 2230-S all along as well.



Another note. I do not know what brand brass this is in the pics, but it is Berdan primed, so watch out for it.

[cfullgraf]

Walkalong, thanks for the update. I am interested in where you end up.

AR rifles just seem to like to shed primers if the load is on the higher side.

[redneck2]

I used some 2230 with 64 grain bullets for my prairie dog hunt last fall. Worked great. IIRC, it's at least a couple notches faster than Varget. Don't have the loads right now.

I do know that it meters GREAT out of my Dillon measure. I bought two pounds for $11 each when Gander Mountain was getting out of reloading stuff. They had eight total. Now I wish I'd gotten them all.

[ssyoumans]

For those that didn't know, the regular AA2230 is also sold as Ramshot X-Terminator. Check out the latest load data from AA and Ramshot. Identical data, down to the PSI.

[Walkalong]

Browsing through that Ramshot data, 2230-S is definitely faster, and not by a hair. Faster than I expected obviously.

[Walkalong]

99 Degrees 34% RH.

23.0 Grs 2230-S, # 41 primer. 55 Gr Z Max.

Hi=3030...Lo=2930...Avg=2980...ES=100...SD=44

1 primers out of 5 showed gas leakage around the primer.

This powder is not going to get me where I want with this bullet. 80 rounds and back where I started. I had hoped to use a powder I already had enough of.

2230-S should work fine for light plinking loads with 55 Gr FMJs. I bought it cheap to make stuff go bang in a pinch if need be, and it will do that.

It usually goes so smoothly, but not this time.

[Walkalong]

Here are two fired unsized cases. One was a part of a bunch that averaged about 3059 and one was part of a batch that averaged about 2973 (Hi 2943). One drops in and out of the case gauge, although the shoulder holds it up a bit from where it was when sized. The other will not go all the way in the gauge. The case heads measure .375 and .377. +/- a couple ten thousandths. The one that popped the primer may have been the "high" (3115) in the batch that averaged 3059 Dunno.


On another note, 23.5 Grs N-133 and a #41 primer gave me an Avg 2917 and everything looked good. Gonna try 23.7 Grs N-133.
