Three weeks ago at my local "old" gun shop I found an original full box of the original Hydro Shock 158 grain lead ammo which was developed here in Watkins Glen NY. The inventor later sold the design rights and this bullet is used today in currently produced ammunition. Best part is I only paid the original price it sold for when it was first marketed. I have tucked this away with my early Model 10, which might have used this ammo.
The internet is great for our gun hobbie pursuits, but there is nothing like finding something like this just around the corner at our local friendly gun shop.
