So I was cleaning my guns after a trip to the range last weekend and got to thinking about cylinder chamber throats...
The guns in question are two different Security sixes in 357 mag as well as a GP100 357 all mid to late 1980's vintage. I went to my reloading bench and got a Hornady 158 grain XTP to use as a guage to measure the chamber throats. On the Security Sixes I could slide the bullet through the throats with with little resistance, but what little resistance there was, was more on the chambers on either side of the "S" stamp.
I tried the same on the GP 100 and found the same to be true on the chambers on either side of the "S" stamp. On the GP100 I could not actually push the bullet through by hand.
On the Ruger Forums I have heard various theories about the significance of the "S" on the cylinder.
Do any fellow nutz here know what the "S" means? On my three guns they seem to point out the smallest chamber throats.
Coincidence?
