I bought a Rossi Puma in 357 about a year ago and just got around to shooting it. With either 38 Special or 357 ammo, after ejecting, the case wall has a gash right at the mouth. I'm concerned that the cases will split after reloading. I have a older Rossi in 44 Mag that shoots great and do not have this problem so this caught me by surprise. Anyone run into or heard of this problem?

The stock Rossis come with an ejector spring that is way too strong and can cause this issue. If you're handy with simple tools and comfortable with disassembling your rifle (with instruction), give Steve's Gunz a call. He's known as Nate Kiowa Jones & 'The Rossi Specialist' in CASS circuit and he sells a DVD showing step by step how to do an action and trigger job on your rifle. Its actually quite simple to do and he walks you through each and every step as well as how to take apart and reassemble your Rossi.

In addition to the DVD, you want to get a metal mag follower to replace the yellow plastic one you have, a lighter weight ejector spring, and if you have that stupid bolt top safety, a plug to replace it. That's all you'll need to turn your Rossi into a slick shooting dream. I have two 357mag Rossis, a 24" oct bbl rifle and 20" rd bbl carbine, that I followed his instructions on to do the action / trigger job and I couldn't be more happy with the results.

This is most likely caused by the casemouth catching in the extractor cutout located at the 12 o'clock position in the breech during ejection. This doesn't look too bad and IMO, will not affect the strength of the brass by much especially if you are not loading to max. You might avoid this altogether by operating the finger lever smartly rather than slowly.

Some call this "pitcher mouth" and it has happened to me with .44 WCF brass in my '92 clone. Since I'm not reloading to max, I just reload the brass as usual and keep shooting. When I get a really bad ding, I put the casemouth in a round steel bar and tap the ding out with a small hammer then take it through the reloading process. Sizer and expander die takes care of the ding, no problems.

Since I was still not satisfied as the dings continued, I took a needle file and rounded off the lower corner of the extractor cutout on both sides then polished off the area with some fine emery paper. You don't have to remove much metal and any dings I get now are very small similar to yours. This is a simple fix and doesn't require any disassembly. If you don't feel comfortable doing things like this, it would be better for you to consult a professional.

Marshal Kane is correct. As I said, the Rossi's ejector spring is way too stiff and can cause this issue as well as a stiff final closing of the action. With the lighter weight spring I suggested it both frees up the closing press on the action as well as not slamming the case mouth into the extractor cutout.
