I used to be a CAS/SASS shooter & have recently crossed over to this, the other, 'dark side'. I've been reloading straight walled cases & shotgun forever, however I'm a newbie to these dolphin lookin' cases. . I've searched this board & read everything I could find but I have only seen one recipe for AA2230 (62gr. bullet). I see a lot of folks here use H335 & TAC , so I don't know if 2230 is a bad choice or not. It happens that I have pounds of 2230. . I've downloaded the AA data for 2230 to load my first batch of .223 but strugglin' to find a recipe using a 55gr. FMJ (MG/HDY) with Win SRP. Neither are listed.  . So I'm hoping y'all could suggest a recipe for this combo for 'normal everday' usage. I'd hate to hafta go find a different powder during this climate. . Thanks, |

My 3-Gun load for hoser stages is a Hornady 55gr FMJ projectile over 25gr of AA2230. I have used both Wolf and CCI primers with excellent results. For long range I use the same load but with a 55gr Nosler Ballistic Tip bullet; this load shoots about 1MOA for me at 200 yards (probably better, but I only use a red dot sight).
Note the above is a MAXIMUM load, so start a little lower in your gun and work up to it. Velocity out of my 18" rifle is ~3160fps - shoots very flat and drops the steel targets just fine. If you want a lighter load, I have gone down to 23.5gr and the gun functioned just fine. |

Quoted: I've downloaded the AA data for 2230 to load my first batch of .223 but strugglin' to find a recipe using a 55gr. FMJ (MG/HDY) with Win SRP. Neither are listed. You'll hardly ever find load data for the exact set of components you're using. Go back to AA2230 load data for 55 gr projectiles, figure out what is 10% below that and make a series of test loads for it working up to max See Step 11 here http://www.ar15.com/content/page.html?id=469 |

Quoted: The data shown is for a 20" barrel. I'm running a 14" & 16" barrel. Hence my not doin' the math. I have 20" and 16" AR-15's, my reloads work fine in both of them, just like factory ammo. Somewhere your load is going to be between 10% less than max and max. There's only one way to find out, make them and test fire them beginning with the loads with the lower charges. Stop test firing when you see the first signs of too much pressure, e.g. flattened primers and be prepared to dissassemble the remaining test loads |

Quoted: Just so you know, the "dark side" normally refers to AK's on this site. Barrel length does not change reloading data. Velocity may be less with shorter barrels, but that's about it. 'Preciate it. don't have an AK. a few AR's... t'were the unholy black powder in the other world. . DOH. I knew that. Musta been thinkn' 'bout makin' major or some such shit.

Well hidden formula. No wonder I couldn't find it.  That and I run a D650, so I more-n-likely skippped that page.  Curious why the denominator is 4 tho? I'll admit I'm a bit confused'd with all the bullet profiles listed in their data. I interpreted the data as a range from 21.1 gr up to 25. gr. for all projectile profiles in order to work up from. I'm used to seein' some extremly light loads for various calibers, but the same lead bullet profile. As an R.O., I've 'caught' squibs but my worst fear was NOT catchin' one before they blew up thier gun! Range time is not a luxury I have presently so I'll start in the middle @ 24.0 gr. |
