Was looking at loading dies for these and a few of them are labeled for both rounds....so maybe this is dumb but is it the same exact brass, loading data etc. Don't have the gun yet (on its way) but was looking at handloading for it since factory rounds are limited. Anybody know?

not exactly. the 356 is semi-rimmed and the 358 is rimless. the parent of the 356 is the 307, which came out to compete with the 308 win which is the parent of the 358 win. i'd check the reloading manual but i'd bet loading data is same as 358.

So...they're the same except for the rim, yes? Which would explain the same dies (but maybe different shell holders). So a 356 can't (or shouldn't) be fired in a 358 gun and vice versa? Only trying to verify cause I plan on getting a 358 also later this year if the gods will it.

that is correct. both .358 bullets.

Great thanks.

For anyone else interested in this thread I found out that the 356 is loaded to lower pressures than the 358.
