"The .38 S&W is slightly larger diameter than .38 special."
The .38 special cartridge is LONGER..... NOT larger in diameter than the old .38 cartridge. The projectile diameter for the old .38 was .359", ( the projectile for the .38 Special is .357") and the case length was 0.78". So the chamber in the cylinder had to be bored .375"deeper to accommodate the longer .38 special.
Wholly Geez, Walt! Go back and re-read what I wrote.
That is, re-read what I wrote and what you quoted.
That is, re-read what I wrote and what you quoted and put in italics
That is, re-read what I wrote and what you quoted and put in italics and then in boldface just to be sure.
That is, re-read the sentence "The .38 S&W is slightly larger diameter than .38 special."
Note that it says that .38 S&W is slightly larger in diameter than .38 special.
Note that I said nothing about which cartridge was longer, only the .38 S&W is larger in diameter than .38 special.
