I know this has been touched on before but wanted to revisit.
Slugged my new 350 Legend barrel and it came out right at .355.
We normally size our bullets 1/2thous over so we're right in the .357 range-but.. lots of very interesting projectiles in the .358 range.
Presupposing no chambering issues could it be reasonable to run a .358 pill?
That is what I would do if I had to. But .356 would be better for your .355 bore.

If you're talking cast, and if it will chamber reliably (take care that the nose profile/diameter doesn't jam in the short freebore), work the load up for it at 357-358/

Haven't reloaded for 350 legend. I size to throat diameter or the biggest that will chamber. So too big is one that won't chamber.
Seating jammed into the lands can really changes things though so I don't do that.

Think I'll pick up a sizer die in .357 and start there.
