Handloader magazine ran an artical on AA-2230c last winter.
They suggest using 2230 load data for 2230c
Also check Accurate Powder's website

i have plenty of data available to me... i want to see how others are doing w/ this combination.
i put together a load using sierra bullets, and at the start load (sierra manual), i blew a primer from too much pressure...
spent yesterday on the phone w/ sierra, accurate, and ultimately the head ballistician from accurate called me, and we chatted for a bit, but i am a little hesitant to go back to this combination at this moment...
the gun runs fine, btw... ran a bunch of factory stuff thru it, and zero troubles, so it isn't the gun.

A few days ago, I shot a .8" 5 shot group at 50 yards using a front bag rest, and iron sights using 2230. This is by no means extraordinary, and Im sure I can bring it down if I try again with this load. I only had 20 rounds loaded up. I used 21.8 gr of 2230, LC brass, Remington 7.5 primers, Hornady 68 gr BTHP Match bullets, OAL of 2.250." No crimp. Ive been consistently getting good groups with the Hornady bullets and 2230. When you say you blew a primer, do you mean there was a hole in the primer? Was it maybe too soft? I used to use Remington primers for 9mm, and sometimes I would see a little soot on the back of the primer, like there was a hole punched through it. They are soft primers, so I switched to CCI for pistol calibers. Did you compare your data across several manuals? I have seen huge variations in data between different manuals.
Give us the load that you blew a primer with.

rockstar- no, not possible. new rifle, feeds and functions everything else (factory and handloads), including my standard powder for the 223 (h-322).
candt- by blowing the primer, i mean blowing it completely out of the pocket, sticking the case in the chamber, ripping a piece of the rim off when the extractor tried to pull the case, and recoil levels around that of a 243 bolt... all from an ar-15... thanks for your data, btw... sierra thought maybe accurate had a bad run of 2230, thus the phone calls w/ accurate. sierra's start load is 24-ish grains (no notes handy), which is what i started at w/ 63 sierra smp's.
judging from your data, and what accurate tells me, sierra's loads are way too hot.

Lymans 48th manual has data for a 63 gr Jacketed SMP bullet, seated to an OAL of 2.260. Starting charge of AA2230 is 23.5 gr with a max of 26.1. These yield velocities of 2926 and 3250, respectively. The manual also has this listed as potentially the most accurate load of the powders they tried. According to the manual, your load doesnt sound too hot, actually well within specs. Is it possible your scale was bumped while reloading, or somehow you put too much powder in the case?
Just checked Accurates website for data and the closest thing they list is a 62 gr HP bullet. Starting and max are 20.4 and 22.8, so according to accurate 24 gr is too much. This is why it pays to check several sources for data. I would go with Accurates data.

heard back from sierra and they tell me my issue is the first they've heard of w/ this particular combination.
i think the lyman 48 and sierra manuals are identical w/ that bullet weight and powder (i have both, but when cross referencing, i typically cross speer #13 and sierra's).
as far as bumping the scale, or somehow messing up the charge myself, yeah, i'd say that could be possible. not likely, but possible. i load on a single stage, weigh every charge, and visually inspect the works before seating a bullet. but, i will admit that something could've happened that was purely my fault.
i'm going to fall back on my last email from sierra, which says to start at 19 and work up.
thanks for the insights.

If you set up your sizing die incorrectly, you'll get too much headspace, regardless of the "newness" of your rifle. The rifle's age is irrelevant. Sounds, though, like an overcharge. If you'd just blown the primer, then maybe you'd have bumped the shoulder too far. (causing too much headspace)
rockstar- no, not possible. i sized the cases i charged w/ 2230 at the same time i sized the h-322 cases. the 322 ran like a champ. factory loads function w/o fail.
i initially thought it was a sizing issue, too, but none of my other handloads had any problem. if it was a rifle problem, it would certainly show up on the first firing of brass - which factory loads are. no troubles w/ factory loads (win, fed, bha).
i have the problem isolated to the powder. either my mistake in charging the case, accurate's mistake in labeling the can or running a fast lot thru, or sierra's mistake in publishing the data...
gonna load tonight and shoot some tomorrow and monday. we'll see if anything new develops.
