While I can not speak to a 357 sig rifle I can say that I love my 357 magnum rifles. I have 2 marlins and a G2 TC contender all are great guns.
I don't see an issue with making a 357 sig rifle... I think the primary problem is demand.
I also know that the .357 sig is bottlenecked but do you know of a handgun caliber that shoots flatter and faster besides 5.7 and tokarev?
Id say a 357 magnum from one of the Magnum automatics.
Edited to add:
This web page shows you what you can expect from an 18inch and shorter rifle
they have most common hand gun calibers. They did this buy buying a T/C Encore 18 inch barrel and chopping it down 1 inch at a time so it should be very accurate.
Shot placement is everything! I would rather take a round of 50BMG to the foot than a 22short to the base of the skull.
all 25 of my guns are 45/70 govt, 357 mag, 22 or 12 ga... I believe in keeping it simple
