58gr superformance 243 load data ?

[hillbilly bob]

Has anybody worked up a load for 243. With 58 gr v max and superformance powder. Can't find any data ?

Hodgdon does show superperformance for a 65 gr bullet. I'd say you could start with 50 gr, which is close to the published 65 gr bullet's max load and work up.
