Simple answer, No.
No, i asume you dont have see .380 pistol and a revolver 38 spl, the .380 and 38 spl ammo share de same diameter boot no the longer, the 38 is for a 38 special revolver tipe and the .380 is for an automatic pistol tipe some people call 9mm short.
If you mean +P ammo the answer is no. It is rated for standard pressure ammo only.
yes, but don't shoot the P ammo too often
you can, but not very often.
Winchester 32 spl 170gr
With modern day primers, and cool dry storage, in exess of 50 years at least.
Possibly the Winchester 110 grain Silvertip. The 125 grain Silvertip is a +P load, the 110 is not.
.38 special IS the correct ammo for a gun chambered in .38 special. Trying to take a round and push it into the barrel is not the way to "test" to see if it's the correct ammo because the cartridge or bullet won't fit into the barrel that way unless you force it. If the gun is a .38 special, you buy .38 special ammo and it will work.
The gun is likely a Harrington & Richardson (H&R) model 925. The caliber is .38 Smith and Wesson (S&W) special, not to be confused with .38 special (SPL). You must shoot the .38 S&W ammo, not .38 spl.
Around $300-$350
