I just got a box . I will be trying them in my 1:7.5 twist 25-06 Ackley improved. It has a new benchmark barrel. That said I think my barrel/chamber is problematic. 52 gr of imr 7828sc produced 3050 fps with the 131 ace. Sticky extraction and totally flat primers. Remember this is a 25-06 Ackley improved case. That said I sat them at 3.400 coal... maybe two close to the lands and it increased pressure. Anyway...we will see if something is wrong.......
