Why arent there fmj round nose in .357 SIG?

[culleniii]

I have looked all around but have yet to find a .357 SIG in fmj round nose and not truncated cone--why is this? and if someone knows a fmjrn please direct. Thank you.

I think it is the short neck area of the case.
I had trouble when I reloaded.
Only certain bullets gave enough neck area.
YMMV

My guess is that the 357SIG was designed around a TC bullet just like the 40S&W, 10mm Auto, etc.

The overall cartrige length with a round nose may or may not work so well in most magazines for the 357SIG.
