[QUOTE="vancewalker007, post: 1891093, member: 66917"] The data for H1000 should be very close for IMR7977. I have shot a lot of both in 2 7mm LRMs and my new 6.5 PRC. The 7977 seems to always need a small amount more charge weight to match H1000. Usually its a grain or less. Start with the low end of H1000. The IMR site shows 49gr H1000 as MIN for 140s. They also list data for several other powders I've used a lot, namely H4350, IMR4350, and IMR4451. Most of these powders should be available some place. [/QUOTE]
