Short answers, properly hand loaded 30-30 rounds will do 1 MOA from a 10" T/C out to at least 100 yards,
Factory rounds with 150 gn bullets should get arounf 1700 fps, and the 170 gn. bullets should get around 1550 or better.
In the Early days of IHMSA, a gun writer [?] did an article for HANDLOADER Mag. on the 30-30 with 10 & 14 " T/C barrels. I lost my collection to a hurricane, maybe Wolfe publishing still has it on file
Since you have 357 dies, the 2nd choice would be the 357 Max. loaded with 180/200 gn. bullets . and you should be able to get 1700 fps with a 200 gn. bullet from a 10" barrel,
