| So I tried the search bar for 4064 powders. Now it said no topics which I find hard to believe. How is this powder for .223 55gn.? |

I tried IMR4064 in my 223's. I could not get enough powder in the case for it to work. Basically, IMO, it's a waste of time and good powder.
I tried stuffing the bullets into the cases. There was major, big-time crunching of kernels going on. So much so, the bullets got pushed back out a way after removal from the seating die. The OAL would grow over time while sitting on the bench. |

There are many more suitable powders for 223 anyway. The various versions of 4064 burn a little slow for good results in 223.

I made up a ladder using 68 Hornady HPBT's a few months ago but I haven't tested them yet and I wasn't trying for top velocity.
As long as you don't mind the long sticks and the slower than optimal velocity you'll probably make suitable ammo with this powder. It's very similar to Varget in burning rate and people use that all the time in .223. |

By an unbelievable coincidence, I loaded up some IMR 4064 behind some 55 gr hornady FMJs just this afternoon.
I went with an even 24 grains of powder and used cci 400 primers. According to hogdon's online data, I figured this load would be on the high end of the pressure range. I shot 9 rounds through my 20in., A1 configured, AR. The recoil seemed considerably less than XM193. However, it cycled all 9 rounds just fine. The last round ejected but did not force the bolt far enough back to engage the bolt hold open feature. Two of the ejected cases were thrown as far back as usual, however the remaining seven were only thrown about half as far a usual. I also have quite a bit of this powder on hand and would like to develop a good load with it. I'm going to try 24.5gr. the next time. |

According to Hodgdon 24gr is just above "Start" charges for 55gr Jacketed. High end or Max would be 25.7gr. http://data.hodgdon.com/cartridge_load.asp |

My plan was 4064 for everything. I have a plan with the 308. I just want bulk ammo. Not worried about tack driving. IMO, that's not a good plan because 4064, while great in 308, is not a good fit for 223. Varget works really well for both. TAC may be better than Varget for bulk ammo because you can accurately throw charges for bulk ammo. My only concern about the above is that a 55 gr bullet is fairly light and may not be optimal for TAC. It WILL work, that's for sure. |
