[QUOTE="Idgunner, post: 2728111, member: 84194"] Just so you guys know, I ran a test with four different primers, Rem 7 1/2, CCIBR4, CCI450 and CCI400, with the CFE223 in my rifle when the temp outside was about 20 degrees. Velocities, according to my Magneto Speed chrono, were all over the map and accuracy was REALLY bad. The hotter primers did not change a thing. I do not have any of the CCI-41 primers. I went back and loaded up 5 rounds with AR-Comp over the CCI450s and made a bughole. I have used the CFE223 for several years in one of my 223s and have been very happy with the accuracy in moderate temps during spring and early summer when shooting rock chucks. This is a new Criterion barrel and I expected sub MOA accuracy with my normal chuck loads. I had to use the loads from my second 223 that shoot 77g STMKs over the AR-Comp to verifiy that the barrel would shoot straight. It gave me a 5 shot group under 1/2 inch. [/QUOTE]
