So, I have been thinking about getting a Nagant Revolver. Mainly for Plinking/Target shooting and as a piece of history, but also (possibly) as another self defence handgun. However,I realize that the double action pull is extremely tough, and that almost modern 7.62x38mm is ONLY for plinking and target shooting, and pales power wise compared to the old surplus stuff (400-600 FPS Difference!), but I intend to use the gun almost only in single action anyways, and I have run across some cheap surplus 7.62x38mm (http://www.aimsurplus.com/product.aspx?item=A76238RFMJ), so, with combat loads that are around, let's say 500 more FPS than commercial loads, how does it rate in power as a manstopper? I've heard that penetration with the surplus is actually great, and it packs alot of extra "umph" behind it, as well as extra stopping power. With surplus ammo, is it at all useful in self defence? I might even plan to use it as an extra "SHTF" handgun since ammo will be easy to stock up on. Even though I do realize that there are better modern options, remember that this isn't my main self defence handgun.
