Hi, fellow reloading guys and gals! I found the site by searching for loading data for the 300 AAC Blackout cartridge. I have been reloading for over 20 years, so am surprised it took me so long to find you. So far I have only been working with the 168 gr. Hornady AMAX and the 175 gr. Sierra MatchKing and Accurate 1680 powder using the newly released Western Powder Data. Both cycle reliably through my rifle using Magpul and C-Products mags at the recommended overall lengths by them. Loads less than 18 gr. for the AMAX or 18.5 gr for the MK do not cycle in my rifle reliably, nor are the lighter loads particularly accurate. Accuracy started to really improve in the 18.5- 19.5 gr. loadings for both bullets, and I will be loading , accuracy testing and chronographing in this powder range as soon as I can get back out. I also will soon be working with the Berger 210 gr. My rifle is built up on a Mega matched billet upper/lower receiver set using a Wilson Combat 16" stainless barrel( carbine length gas system and 1/8 twist rate). I also am running an MGI 6 3/4 ounce buffer in a carbine tube with a standard weight recoil spring. I hope this is helpful, and I look forward to spending lots of time here!

Does anyone know where a Ballistics chart for both Max Loads and subsonic loads in 300 AAC could be found? RD
