Bought a Rossi M92...has interesting diet.

[N40W111]

Howdy pards...
Been awhile since I posted but I got out the plastic courage the other day at my favorite gun store and bought me a new 16" Rossi M92 .357 in stainless. Now I know I'm probably gonna get chastened for buying the 16 incher but I already shoot an 1894C fish gun too.
This little Rossi was so pretty, I had to have it.  My first 92 since I have been paying attention to 92's...(I owned a 20' inch Rossi several years ago before CAS caught my attention.  I didn't reload at the time and it was a finicky little beast so I  let 'er go).
I'm a .38 Special all the time shooter.  I also carry a S&W 438 Bodyguard for CCW.  I usually load 125 gr. RNFP for most of my shooting and the Marlin loves 'em but the new Rossi was spiittin' live rounds out the top like nuts...so, I went back to the bench and loaded some 158 gr. LSWC behind a 3.2 gr. drop of TrailBoss and tried it again.  This time perfect results, no hangups or premature ejects, or anything else.  Must have been the OAL is all I can figure.
This gun cycles pretty well out of the box although I'd like to send it to Steve's Guns for a workover but I understand he's running way behind.  Anybody else using TrailBoss with 158 LSWC's in a 92?

Sorry, I'm a .44 caliber man (.44-40, .44 Extra Long Russian...aka .44 Mangle-em), but I can tell you your problem was definitely OAL.  It isn't just the Rossi; the original M1892 Winchesters were scaled down M1886's, but designed for use with the same cartridges for which the M1873 was chambered, i.e., .44 WCF, .38 WCF...aka .38-40, .32-20 and later 25-20.  The problem with "scaling" up or down on a successful design is that you get tolerence build-ups in the parts, and the feeding gets more sensitive to cartrdige OAL.

Looks like you found the right combination for smooth feeding.  Enjoy!

I've had my Rossi .357 for a long time.  It started doing like you said after I shot CAS for about a year with it.  But not Before that.  I usualy use a 125 Truncated cone bullet.
I did some research on the "spitting live rounds out" problem and it sems to be a combination of overall cartridge length and the with between the bolt guides.  My local smith put a shim behind the the removable guid and made the gap that the rounds come up through narower.  Just wide edough not to jam.  I also started loading my .38's a bit longer.  Not full .357 length but the crimp isnt quite in the groove on the bullett.  both seemed to help and it runs smooth as can be now after many thousands of rounds. 
I like it so much that I am thinking of sell my uberti '73 to get a rossi puma in .454.

Since you just got a Rossi 92 you may find this interesting.

I am presently using Magnus 125 gn RNFP in front of 3 gns of Trailboss with an OAL of 1.425" and it is running perfectly.

I have an EMF 1892 Hartford in .44-40 and had an action job done on it. It works pretty good but once in a while I end up ejecting a live round. That may be me not levering it with enough authority at times.

My main match rifle is a Uberti 1866 Yellowboy from Taylor's. It is chambered in .38 special. I use a special 147 grain TC bullet from Moulton Lead  (www.moultonlead.com)  in Vermont. It makes for a longer OAL of 1.555". With using standard .38 special cases along with 3.0 grains of Trail Boss, it has been trouble free.

Thanks for the replies fellas...
Johnny, I may have to try some of those Vermont bullets.  OAL definitely looks longer on the two that are not 158 grain.  Less bullet weight but longer OAL...interesting.  I took the Rossi out again yesterday and ran a box of 50 of the 158 LSWC's again just to see if I was imagining things....nope.  Every cartridge cycled flawlessly.  I can get these 158's pretty cheap from a local supplier and they're cast very nearby me (10 miles) if I wanted to go direct to the vendor.  I think I'm gonna stick by 'em for a while just to see what happens.
Anyways...I'm in mega love with this little Rossi.  Now to start replacing the magazine follower, etc., etc.,etc...it's a sickness.  

At least the wife says it's a sickness but she doesn't bat an eye at a $25.00 can of high-performance hair spray!!!!

Howdy N40W111,

The 125 grain and 158 grain bullets are seated to the crimp grove. The 147 grain bullet has no crimp grove.

The overall lengths are as follows:
125 grain  1.445"
158 grain  1.425"
147 grain  1.555"

t that is called the snake bite and it is designed to be loaded in 38 spl cases but give 357 OAL. Look up Springfield Slim at Whytes Leather. Tell him Fairshake sent ya. He has pics on the site.
