I experimented this weekend with CCI BR4 and CCI 450 primers along with several different powders. There were some promising results using my BHW barrel chambered in .264 LBC. Groups were shot at 100 yards. Conditions were near perfect, with an intermittent tail wind of 2-3 mph and a temp of approximately 86 degrees F.
30.6 grains of CFE 223 with a CCI 450 primer yielded the best result with a two hole clover leaf and two of the three rounds in the same hole. Several other loads may require further review (loads using IMR8208 XBR may have been influenced by minor differences in charge weights or shooter error). However, these loads did result in slightly lower velocities when compared to the best CFE 223 result.
Brass/primers did not exhibit any pressure signs.
*DISCLAIMER* I began with the intention of loading five rounds per load, but foolishly did not count how much brass I had. Thus the reason why the 4 groups in the middle of the target had five rounds and the others only three. I accept responsibility for any fliers
Hope this is informative as I am still getting the hang of posting around here.
