Hodgdon CFE223 Test (.223 Rem)

CAUTION: The following post includes loading data beyond currently published maximums for this cartridge. USE AT YOUR OWN RISK. Neither the writer, The Firing Line, nor the staff of TFL assume any liability for any damage or injury resulting from use of this information.

I tested CFE223 in my 22" DPMS AR-15 with both standard CCI 400 primers and magnum CCI 450 primers.

I loaded 8 rounds each of 26.0gr, 26.5gr, 27.0gr and 27.5 gr. I also loaded 8 rounds with the CCI 450 and 28.0gr to test a max charge for pressure.

I measured velocity 15 ft from the muzzle with a Competition Electronics ProChrony.

Below are the results in a pdf file. Please check it out and let me know what you think.

I was planning on measureing the groups, but all groups were over 1.5" for 8 shots. I am not sure what was going on, as I have gotten five shot groups under 1" with other loads. So this test is strictly a velocity test comparing CFE223 and the two types of primers.

There were no signs of pressure noted on any spent brass.
