Higginez, Yes, 24" 1x8 107 SMK over Retumbo, some people frown when i say Retumbo, but give it a try it works way better than 4350 or h- 1000 or the other powders i have tried. Rio7
What charge weight are you using? Retumbo shot ok in my 243/105VLD combo but 7828 shoots lights out.
The 88gr Hammers aren’t to bad either if you are forced to use lead free.
