I am wondering if anyone has the load data for a 243 winchester using IMR 7828 and a 65 grain hornady v-max bullet. Because I am trying different powders recommended by other users on the forum and by a couple of gunsmiths. Thanks

They don't list IMR 7828 so I don't think I'd go there.
 
IMR7828 is too slow for the 243 Win and 65 gr bullets.
I would suggest trying IMR4895.

7828 is the best powder for 95gr + in the 243. My 243 use to do 3250 fps with a 100 gr with this powder.

work up from 42 please
 
I plugged in a 63000 psi max.

(For reference the 308 win is almost 65K psi./52000 cup)

Cartridge : .243 Win.
