Just found this: http://www.smith-wesson.com/wcsstore...ver_Manual.pdf
not 100% sure if its exactly for your gun, but you can either call them or email them, just check out their website.
I have recently acquired a Stainless S&W Model 66-4 with a 4 barrel.
Anybody know how to find its birth date?
The serial number is CAE 1XXX.
Is it safe to shoot 125 grain .357s through it?
As I researched the gun, I ran across several warnings about shooting 125 grain .357s through Model 19s.
I dont know if it applies to model 66-4 or not.
Thank you in advance for your help.
Thank you for that information
