Just a quick update.....I found the "end" with my 300 wby tube that LOVES Retumbo...(see earlier posts) I hit the wall at 93 grains. Got the hitch at the top of action stroke and had shiny ejector marks..... I won't go there again. I also had a sub 1/2 group at 300 yards!!!
Unfortunatly, I didn't have my chrono set up...to much work seting it up in two feet of snow. I will crono the 91 grain load in the basement next chance I get. The groups were not steller at 91, but at least I will have a base line.
Anyone using it in their Edge/Lapua yet. Just got my new Edge up and running. Going to test H1000 to the end and maybe tinker with retumbo and RL25/33.
