SST and GMX Superformance shoot very well... I suspect the Amax Super will shoot awesome also... Were you using the AMAX or the AMAX super? Thanks in advance.I went to a long rang precision shoot last month with my RPR in 308. I had FGM and Hornady AMAX. The AMAX 168 Grain was the most accurate round of the others I tried.. AMAX 168 for the 308 RPR from now on. Went out to 612 yards whic is the max distance and had a few shots in 1 hole..
