The difficulty of manufacturing a stellite enhanced barrel.\n\n13:50\nWhat is QPQ,<br> etc?\n\n15:10\nNitride process is very similar to the older 1800\u2019s process of case hardening.\nWhat is case hardening? \n\n16:05\nHow deep does the nitride process penetrate into the steel? Case hardening is usually only a superficial layer,<br> for example.\n\n17:20\nNitride for military arms?\n\n18:15\nExtreme example of high velocity projectiles,<br> is that better with chrome or nitride?\n\n19:44\nStainless steel that\u2019s used for barrels isn\u2019t really the \u201cstainless steel\u201d we think it is.\nWhy are stainless barrels considered more accurate?\n\n20:54\nDiscussion about different methods of rifling a barrel.\n\n27:10\nCold Hammer Forging invented by Germans in WW2 to accelerate barrel manufacturing.\nUSA used cut rifling primarily during WW2 and those machines are still being used today.\n\n27:45\nWhat is cut rifling?\n\n29:00\nReplacing a cutting bit for cut rifling,<br> what about button rifling?\nDeep dive into button rifling process.\n\n29:50\nDiscussion about progressive twist rifling.\n\n31:41\nAccuracy then and now,<br> what is acceptable?\n\n34:05\nOriginal M16 pencil barrels,<br> how were they manufactured?",<br>"json_metadata":" \"tags\":[\"interview\" ,<br>\"image\":[\"https:\/\/img.youtube.com\/vi\/e2X1iaQbjg8\/0.jpg\" ,<br>\"links\":[\"https:\/\/www.youtube.com\/embed\/e2X1iaQbjg8\" ,<br>\"app\":\"steemit\/0.1\",<br>\"format\":\"markdown\" " |
