Wayne59, The main reason for the longer case is so that you can send heavier bullets down range at a decent speed. The British used Black powder to do many of their proof loads, they may still be doing it for all I know. Black generates More pressure in cartridges than in muzzle loaders because it is a better sealed system. These Russian guns have extremely small barrel diameters for their calibers, and extending the chambers in one might prove to be catastrophic if you don't know the yield strength of the steel you are working with. I am encouraging this fellow to use some caution for safety sake. I feel that encouraging anyone to extend the chambers on a gun with minimum barrel diameters is like playing Russian roulette with someones life. Bob |
