Looking for info on the 357 SIG load, Bullets to be exact. From all Ive read it appears that a 9MM .355dia will work in a 357 SIG. The 357 Sig calls for a .355 round. Does it matter that it's TCP ,RN or whatever. As long as I work up the load and they feed I should be OK right. Some thing tells me I answered my own question.............. Any input would be great.:)

Some 9mm bullets will work like the Hornady XTP 124 gr., but many do not have the correct profile for the short neck on the 357 SIG ...
this link has some info that will help....
Lots of good 357 SIG info here....

NO! Not just any 9mm bullet will work. You MUST use a TC design.(Um TC stands for truncated cone). The 357 sig has such a short neck that in order for the neck to grip the round nose of a normal 9mm bullet AND be the right OAL, the neck is trying to grip the ogive of the bullet instead of the full caliber sides of the bullet. Result is the bullet being loose in the neck, and moving deeper into the case when being chambered.
The TC design of the 124 grain Hornady XTP bullet,(or similar shapes), allows the neck to have full purchase on the bullet.
Also, you must lube the cases just as you would a bottle necked rifle case. There's a work-around to avoid that but someone else can tell you that.

Assuming we are talking target rounds and not SD rounds, take a look at Rainier 124 gr flat point, lots of positive comments on Midwayusa about people loading those for 357 Sig. I have a small stash of Berry's 9mm 124gr flat nose hollow point that I think are going to work well also. 357 sig and .40 have a similar and distinct profile. Look for a bullet of that same shape (as the one's I've mentioned) and you should be in great shape.
