Seafire: I have owned a bunch of 223 Remington Rifles over the last 4 1/2 decades but looking through all my loading log notes for them I have never tried IMR 4064 in ANY of them!
I will have some time once December gets here and will give your "Accuracy Champ" powder a try in a couple of my 223's.
Thanks for the tip.
By the way is there any chance I will be bringing my Rifle home in a basket with this IMR 4064 load?
I do use a lot of IMR 4064 in my 22-250 Remingtons and of course almost exclusively in all my 220 Swifts but never in the "littler" 22's.
Thanks again.

VG,

I am loading the case with 25 grains...there is load data that runs it up to 26.5 grains...and they must be using a jack hammer to compress it all in there...

25 grains is right to the shoulder...

and with the velocity, I am guessing its pressure is down in the 45,000 CUP range...

with 40 to 55 grain bullets, I don't think the 223 can get enough 4064 into the case to give ANY pressure problems..

actually since trying it, I have noticed that 4064 is in the Sierra and Nosler reload manuals....

what also surprised me is a string or two of 10 shots fairly rapidly, the barrel didn't heat up as much as you'd expect on a case full of this much powder..

depending on what I see for the size of deer running around the wooded area I hunt, I have some Barnes 53 grain X Bullets loaded up with this charge for my featherweight 223, just in case I decide to carry that when I am guiding for a few boys I will be taking out hunting...

Seafire: Received, thank you for that additional information!
