I've been looking at the loading data in the stickies, and im noticing that there is AA2230 and AA2230-c. What is the difference? Googling yields no results.
I ask because one load says they used 26gr of AA2230 for a 55gr bullet and got the same velocity a load of 24gr of AA2230-c but with a 69gr bullet. How do i tell which i have since it only says 2230 on the bottle? |

Not sure if your manual means compressed or not, but there has been a AA2230C sold in the past. It is a "data" powder and was sold with some limited loading data for the reason it was not the same as there regular 2230 powder.
http://www.accuratepowder.com/datapowder_dp2230c.htm There was a 2230S data powder as well that also came with its own data sheet with just a few recommended loadings. I happen to have a pic of this one handy....

. The C does not mean compressed. Accurate Powders distributed a surplus powder Called 2230-C. It is not the same as 2230! If your bottle says 2230, then it is plain old 2230. 2230-C was sold in 8lb jugs and is no longer available although there is plenty of it still in the hands of reloaders. Here is the scoop on 2230-C from AA web sight., it's says to use AA 2460 load data as is, not 2230 data. http://accuratepowder.com/datapowder_dp2230c.htm |

Thanks for all the replies. I know that there are several stikies on this stuff, i have searched through them and i havent found much load data for 2230, if anyone knows a good source please point it out.
THe reason i ask i because all the stuff i see seems like low velocity .223 loads not 5.56 |

According to my hornady reloading book under .223 service for a 68gr match bullet they say 24.2gr of 2230 is MAX and is at 2700fps, while the other powders they have listed go to 2800fps as their max. I say low velocity because the 75gr load they have below it has 4 powders that they say can do 2700fps safely. I have searched my reloading book but cannot find this answer: Why can i use 26gr of powder for a 55gr bullet, but 24gr is max when using heavier bullets such as 68gr? |

The heavier bullet presents a greater resistance to the push applied by pressure in the chamber, so in order to keep the pressure about the same, the charge weight of gunpowder needs to be less. |
