Acquired an old 38-200 British Service revolver that S&W says was made in 1942, Although the finish is pretty bad, the gun is solid and the cylinders and barrel are clean and free of rust, corrosion and pitting. Along with the gun came an unopened box of Remington 38 special ammo. I understand that the 38-200 was meant to fire a 38 cal, 200 gr bullet, and from what I can tell, it looks like the cylinder is original to the gun. Assuming that is correct, is it safe to fire the .38 special ammo? I want to re-finish the gun, and I understand that doing so will diminish any antique value, but since I never intend to sell it, and will probably give it to my grandson, the first order of business is verifying the ammunition. Any help will be appreciated.
