Studies of wear charactistics of three different gunpowder gases

In this report a study of the gun barrel wear characteristicsof three different gunpowders are performed. The three different gunpowders are: Bofors NC 1214 NEXPLO (NEXPLO), BOFORS NC 1214 EURENCO (EURENCO) and PB Clermont 347 (PBC 347). We study the wear both theoretically and experimentally. We find that PBC 347 gives the least wear.
