Retumbo seems to be best suited for about 160 grain bullets and up. I'm
Just under bergers max load for 180 bergers in my 7 mag and I get 2970 fps in a 26.5 inch tube. I couldn't be happier with it

Hard to beat Retumbo with 180's going 2950+ fps.

Im shooting 168gr Berger V's out of my 7 mag. Tried 4831SC, H4350 and H1000. The H1000 has shot the best groups so far. Need to find a chrono...
