So I'm presently loading some 223 for an AR15. I've got 25 LC brass prepped, and 15 IVI cases. Going to be using H-335.
I volume measured the cases. The LC's average 30.33 grains of water, and the IVI average 29.66. An average difference of .66 grains volume between the two head stamps.
How, exactly, would you handle this on a load work up for the combined set? How to you handle any load workup for mixed brass? Is there a "rule of thumb" if you've actually measured them as I have done in this case?
Waiting to choose my loading, and thanks for any advice,
