| Been reloading 308, 50BMG and 44 mag. Getting ready to do 223/5.56 with Hornady 75 gr A-Max for the 1st time. Looked at hodgdon reload site to see what powders to use. Am familiar with varget, 8208xbr, 4064 and 4166 and have reloaded with these in 308. The others I have not. I have all 4 powders already so if possible, want to use one of them. What would be a good powder for a carbine AR for the 75 gr A-Max? |

24gr Varget, 22gr IMR4064, about 0.020" jump (OAL should end up between 2.400-2.500"). Be sure the seating stem doesn't do anything funky to the ogive or tip. ETA: when single-loading, insert round into the chamber before dropping bolt to prevent bending the bullet in the neck. |

Probably need to work on your skill set before helping others. You need to understand bullets that are appropriate for AR's and what are not meant for magazine length use. One should consult reloading manuals for hints on best options for powder and then relate that to what you have on or can purchase.
Just cause you want least expensive does not mean it is a viable option. Look at Nosler Pro Shop for blemished bullets for cheap bullets like the 69gr or 77gr OTM. If you are going to load for volume use look at ball powders for easier measurement. TAC works great with heavier bullets in the 223. |

Quoted:
You can load them to mag length, provided you trim to 1.73 and use a finer ball powder (Ramshot TAC). I have already loaded 50 for accuracy testing, but I'm not expecting anything great, however, I'll know for sure this weekend. Post what you find out. Just interesting to here folks who try stuff instead of just reading. I don't plan to get an AR15, prefer my AR10's and 308 bolt's. To each his own. |
