Was going to post a photo from the Speer Manual Number 8 with the RL-11 data I was talking about but I don't want to get into any copyright issues. I read somewhere once that the Speer Number 8 manual was a "hot" load edition of the Speer manuals and when compared to some later editions that would seem to be probable.
The book shows the following RL-11 loads with 180 gr Flat Point out of a 24" Enfield custom:
Start load 39.0 gr 2307fps Middle load 41.0 gr 2402fps Max load 43.0 gr 2477fps
It also shows RL-11 maxing the Speer 220 gr Flat Point at 2157fps
Never have used RL-11 but that is some scooting along velocities out of a 35 Rem.
