I have a brand new 3 in 63. It shoots great and is super accurate but I've noticed on all chambers the brass bulges slightly by the rims where the extractor is. S&W customer service says it's normal as long as extraction is easy & no case rupture. Mine extracts great even after extended shooting. So my question is has anybody else experienced this?

Can't say that I have ever looked at spent cases out of the revolvers... still don't think I will. As long as it all goes smooth I worry more about fouling at the other end.

I looked at some fired brass from my 617 and there is a VERY SLIGHT expansion of the casing around the extractor area of the spent cases. I have not experienced any difficulty with extraction. Since you say you haven't experienced any extraction difficulties, I suggest you just ignore it. That's what I plan to do.

IIRC, there is a very very slight bulge in my spent .22 casings in my 63-5. Ejects fine, though.

Unless you are reloading .22 LR, I wouldn't worry about it.

Thanks guys.

My 317 and 617 have slight bulging but no problems . I did have an early production 317 that expanded the whole rear of the case and locked up the gun and S&W replaced the yoke and cylinder and it has been fine since but still has a tiny bulge that causes no problems and that gun now belongs to my wife.

You got nothing to worry about. Enjoy!

I've tried inserting spent .22 cases into my GP100 .22 so I can dry fire, and they won't slide in all the way, I guess from bulging.
