H870 or H1000 Loads for 65x284 ?
I need to work up a load for a savage 111 in 65x284 using Berger 130 or 140s. I have seen and herd a lot of guys using retumbo powder with good success. I However have a bunch of H870 and a little H 1000 on hand. According to burn rate charts the 870 is right next to the retumbo powder. I cannot find any data using it in the 65x284. does anyone out there have any leads or ideas?
