[QUOTE="SPR123, post: 766167, member: 54999"] Len, I tried the Retumbo and the H1000 over the weekend in my 7mmLRM. From what I read, the Retumbo was going to produce more speed over the H1000 with the same powder charge. I wanted to deliver the 180 VLD's above 3000 fps. I loaded 5 rounds with 72 gns of Retumbo and 5 rounds with 72 gns of H1000. The Retumbo had an average muzzle velocity of 2985 with a 2994 High and a 2976 low. The H1000 had an average of 3028 with a 3040 high and a 3017 low. So i guess there is no real advantage of going with the Retumbo unless you look at the ES of 18 on the Retumbo and 23 with the H1000. I'm still testing both but the H1000 looks like it might be my powder for the 7mmLRM. Have you tried anything different from your original post? [/QUOTE]
