[QUOTE="gte901m, post: 1671855, member: 80740"] IMR4831 and H4831 are materially different. The IMR4831 load you developed will not translate directly to H4831. The H1000 discrepancy you referenced is typical for 7mag data. Early 7mag data was optimistic with velocity, and modern data seems to be anemic. Using case head expansion as a guide, 160 partitions maxed at ~71 grains in my rifle, and the accuracy nodes was ~69 grains. A 160 AB should be similar. Start 8-10% below 71. As was mentioned above, calibrated your scale; a compressed load with a starting charge weight is abnormal. [/QUOTE]
