Hi,
I know it cheeky, but Can someone give me the quick load info on :-
Cartridge : .223 Rem.
Bullet : .224, 53, Hornady V-MAX BT 22265
Cartridge O.A.L. L6: 2.260 inch
Barrel Length : 20 inch 1:9
Powder : IMR 8208 XBR
Primer : Rem 71/2
Case capacity in grains of H20 : 30.1gr
Currently running a load of 25.6 gr ,
but would like to see what it says for 25.9gr
Thanks

Many Thanks ..
I notice that the capacity in the graph is very low at 26.885 gr
My Winchester brass gives me a capacity of 30.1 gr
I take it that this would give very different pressure results ?!?
Cheers
Al.

Firstly , before I start this post...
Many thanks to Triffid for looking into this for me .
as I pointed out in my last post, where I tried to be humble.
Now,
Unless I am mistaken that clearly says : usable case capacity : 26.893 grain H20
Not usable case capacity : 30.1 grain H20
i believe 26.893 is the default setting
I don't know of many modern 223 cases that small ... 99% these days are 29gr or more
The internal size of the case would have a dramatic effect to the PSI. Which in turn has an effect to the FPS
I know from my own testing that a 25.6gr load gives me an average fps of 3155
Well under what is stated in the above graph / table with the same load.
Many thanks

It states usable case capacity, so I would assume that it is allowing for the space the bullet takes up in the case against the COAL but I may be wrong it's been a long time since I've played with my quick load

The difference is in the volume of the seated bullet. In this case 3.215 grains of water.
30.1 - 3.215 = 26.885

Correct.
Was calculated with 30.1gr of overall case capacity, as requested. Unless the OP measured with a bullet stuffed in...?

Many thanks ..
And thanks for pointing that out..
I am shocked though, as my data up to 25.5 gr powder is vastly different from the data listed
Hence my questioning of the capacity.
Again, thank you !
