I have a Ruger Security Six in Stainless with 6" barrel. The chambers seem to be oversized. Fired cases do not fit in other .357 revolvers I have or a case gauge. Fired cases in my Dan Wesson and Smith 686 fit in case gauge after fired. This happens with light loads as well. Other than wearing out brass sooner, does this pose any issue? Is this common with the Security Six? Does oversized chamber allow wiggle room for heavier loads as the brass stretches some before pressure is applied to cylinder walls?

Have you tried using a pin gauge to determine exactly how large the cylinders are?
If you don't have pin gauges, then try dropping an oversized bullet down the cylinder until you can just push through with finger pressure. measure the bullet and you will at least know where to start with a diagnosis.
You might also mark the brass fired from the ss6, and keep it separate for handloading for that particular gun. Don't resize and you may get a few more handloads from that brass.
I wouldn't worry too much if you're getting decent accuracy now.
I had a S&W 25-5 with way oversized cylinders. I never noticed any overpressure conditions from stretching brass.

It's the base of the chamber at the case head that is oversized. Accuracy is good for sure. I suppose that resize could be done halfway down case and just use them for that particular gun. That would definitely pro long the brass. Great point. |

I have a Ruger Blackhawk with oversized chambers. I used the same batch of Winchester brass for over 15 years with no problems.
When I acquired a Linebaugh built 45colt Seville, the ruger brass wouldn't come close to fitting.

Have you had brass life problems? How many loads do you get before you start getting failures?

I guess it matters how many times they used the chamber reamers before changing them out. When I was living in Oklahoma I was a dealer and I bought five Conn State Police Ruger Stainless Security Sixes 357 magnums. and sold them to friends. Some wanted some cast reloads with them so I loaded them up with 150 grain RCBS SWC's. I sized the cases with Bonanza dies. Same loads fit my Model 19 S&W really well, dropped right in the chambers. Well, I got calls the ammo would only go in half way in those Rugers. I had to redo all of them. So I'm surprised to hear of a Security Six with giant chambers.

Have you had brass life problems? How many loads do you get before you start getting failures? No issues with brass life. Only reloaded 3 times so far with new Starline brass. The gun is relatively new to me. Just posed question because my other .357's don't have that issue and I shoot max loads for this caliber. My Smiths and Dan Wesson's have lost count of reloads. |

Just wondering. I know 357's can go well past a dozen loadings, so if you get 5 or something low like that, I would certainly understand your concern. |
